Oh man. That sucks. NY is really fun. Why couldn't you go?

I don't understand why I didn't go. He said that will take both of us and then one week before going he have changed his mind. He told that he doesn't have enough money.

I would be kind of mad and dissappointed with him. You could have offered to pay your own way!
