"after" means right after some other event. so if u tell someone that u'll do something after that person did something else, it is common knowledge, that u have to do it right afterwards, not leaving any time inbetween!
I'll tell u AFTER u told me something else.
> that means, u gotta tell it right after that other person told u!
