Oh man, that sucks. Were they trying to keep the trip a secret from you?

My mom called and told me because she felt bad.  My siblings are taking them for free so I'm not mad at them but I'm definitely mad at my brother and sister!  They didn't say a thing, even when i mentioned it.

That sounds like it would be really disappointing. Are you close to your brother and sister?
