Don't share the cake. They are probably too full anyways.

Surprise!

Usually, a surprise is pleasant, but sometimes it’s finding out how much your “friends” value you.

then maybe they aren't your friends

I've been in a situation like that before. I know it's really heart wrenching and devastating now, but cut them out of your life. If they can't value you as much as you value them, then they are not going to start anytime soon. Trust me, when college/work/adult life comes, those are when you make mature and less superficial friends.

I guess it's time for some new friends!!

Rip them apart and devour their previous dinners from the inside, in the true spirit of a birthday.
Actually dont. Still, your "friends" are not very considerate of you.

I don't believe I would call them friends. I probably wouldn't do anything to ruin my birthday (thereby making myself feel worse), but I would carefully reconsider those whom I would choose the call friends in the future. By the way, did this group include your "best friend" or boyfriend? If so, cut them out IMMEDIATELY, as they clearly didn't consider your feelings AT ALL, on your special day.

They are NOT your friends!!

that blows. same thing happened on my 22nd birthday

Smh your friends suck lol
