Remind he or she，lol. Something like I want to have a meal together or go to see the movie. Of course it is on him or she. lol

Oh, and to repay the favor you did by helping me with my Chinese I'll help you a bit. It's better if you phrase it like this: "If the person you care about the most didn't remember your special day, what would you do?"

Hi Kyna Don't take it too much to heart (don't take it too seriously). Sometimes we men aren't very good at paying attention to those kind of things, it doesn't mean that we don't care. As long as he treats you well the rest of the time, don't worry so much. If he doesn't, then just forget about him. Of course, you could still give him the cold shoulder (i.e. ignore him) for a few days to teach him a lesson ;-). Good luck.

I would give him or her plenty of hints next time. You could also contact this person offering to catch up since you weren't able to on your special day. Example: Hi Bob/Jane, I am sorry we couldn't catch up on my birthday last week, why don't we have a coffee tomorrow?

just smile forget it
