You know when something is just nonsense sometimes or just like doesn't have any rational logic, you just have to take a second to like try to understand it. This idiom has connotations of focus, concentration, patience, perseverance. Last weekend there was actually this really special sky experience happening. The northern lights or the aurora, aurora borealis I think it's called, where the sky glows green or purple. This was happening and you could see it from London, which is really unusual, and all in the south of England as well. Usually you can only see the northern lights, obviously if you go somewhere like Iceland, or if you go to Scotland right to the top of the country in the north. So this was amazing and it took me a while to wrap my head around it because how can we see that down here? How is that possible? How? How? Anyway we tried to go and see it and we missed it really. We were a bit late to the table unfortunately on this and we saw a kind of glow in the sky but some of my friends they told me they saw like swirling purple sky and clouds and it was stunning, like absolutely magic. But it just took me a while to wrap my head around it because I didn't believe that it could be possible down here so I used that idiom. Number six, to be bouncing off the walls. To be bouncing off the walls. This is about having lots of energy. You have all this excitement and energy. Now you can use this if you want to describe the feeling of having too much coffee, which is often what I have to describe. I now have a rule of just one coffee, one coffee in the morning, that's it. But you know when you've had a lot of caffeine you feel like you're bouncing off the walls, you've got lots of energy. So this has connotations of energy and good vibes. It can also reference having a lot of nervous energy, you can say I'm bouncing off the walls, I'm just so I'm so nervous and excited. I remember when I made my first YouTube video and I was like kind of excited and Tom was just like look just go out for a walk, you are bouncing off the walls, you are full of nervous energy, and yeah that was the that was the feeling. It had nothing to do with caffeine, it was more anticipation and excitement because I was actually really excited to do it. We use this a lot with children, especially when they've had sugar. You'll hear a lot of parents saying oh Sophie's bouncing off the walls at the moment, she's just had an ice cream or something. Number seven, a ray of sunshine. A ray of sunshine. This idiom is about people, so when you're describing someone's character or their personality, which is actually really important for daily English, you never know when you're going to need to describe someone. It could be anyone, your family member or a friend, and this is just about someone who brings happiness to people, okay. They're very positive, they have a lot of good energy about them and my mum is literally this. My mother, oh my, she is such a ray of sunshine and I remember my grandparents when they were going through a difficult time with their health and everything was a bit doom and gloom, which means a bit depressing, they would always say that my mum was like a ray of sunshine because every time she went round to their house she would kind of just cheer them up with her existence really and her cheerful way and I always remember them saying that to her, so yeah mum you really are. This idiom has connotations of warmth, positivity, hope and kindness. Number eight, a hidden gem. Do you know what a gem is? A gem is like a diamond or a precious stone, like a ruby or an emerald. The idiom a hidden gem is about something that perhaps hasn't been discovered by a lot of people, it's not known about by a lot of people, but it's also maybe something to be kept secret because you don't want everyone knowing. For example, I know a lot of hidden gems in Cornwall, which is one of my favourite places in the UK, and I don't know if I'm ever really going to tell people exactly where they are because they are secret. They are as valuable to me as diamonds, so they are like gems to me, but they are hidden because not that many people know about them, they're off the beaten track, they're not on the tourist path, okay, so if you want a recommendation for a hidden gem in Cornwall you're gonna have to get to know me on a deeper level.
你知道，有時候有些東西簡直是無稽之談，或者根本沒有任何合理的邏輯，你只需要花一秒鐘的時間去試著理解它。這個成語的內涵是專注、集中、耐心、堅持不懈。上週末，天空中出現了一種非常特別的景象。北極光或極光，我想它的名字叫 "北方極光"，天空會發出綠色或紫色的光。你可以在倫敦看到北極光，這很不尋常，在英格蘭南部也能看到。通常你只能看到北極光，很明顯，如果你去冰島這樣的地方，或者如果你去蘇格蘭北部的國家之巔。所以這太神奇了，我花了好一會兒才想明白，因為我們怎麼能在這裡看到呢？這怎麼可能？怎麼可能？怎麼可能？總之，我
