If you're making an effort to be with your parents for two full weeks each year for the rest of their lives, which covers the main holidays, birthdays, and a bit extra, you still have already spent more than 90% of the time you will ever spend with them, even if they grow pretty old.
如果你努力在父母的餘生中每年陪伴他們整整兩週的時間,包括主要節日、生日和一些額外的時間,那麼即使他們變得很老,你也已經度過了90%以上的陪伴時間。
