Would 당신 hate spending your birthday at another persons birthday party and 당신 didn't want to be there in the first place ?

If they really wanted me there, not at all! why ruin both our birthdays!


And if they didn't want me there,I'd suck it up and have a good time.

Hell yeah! Well........it depends

Chances are the other person wanted me at his/her birthday party, and if that is the case I would put my frustration aside and celebrate their birthday.
A birthday's just a birthday. I can always celebrate my birthday at another time.
