I sometimes pretend that people's pi-day celebrations are actually stuff for my birthday
Why do you want to do that?
I just wish that everybody celebrated my birthday since it is on 17th of March.
I guess it's nice to have a fantasy. Just don't demand people do things for you. That will make them resent you.
Sure, maybe I should just check if there is anyone else that wishes to celebrate their birthday on March 17 th .
That sounds good and it is okay to want people all over to want to celebrate you. It doesn't hurt anything to fantasize about it.
