Wishing my mathematician friend a happy birthday
- I almost forgot these holidays, they are almost meaningless to me, at most they make me eat a little more that day, when they mentioned today is their birthday, I only knew today is their birthday
- This is somewhat embarrassing, as a friend I didn't pay attention to this, even though they thanked me for the belated birthday wishes, I still feel it's not enough
- But I can't do anything, they are now in a different time zone from me, I can't fly over from here to give them a surprise
- Since I can't do anything, I'll just write something to celebrate their birthday, this is the birthday gift
- Thank you for your help this year, wishing you a happy birthday, my friend
