I know I'm just another voice talking to a brick wall, but I can't help myself from asking:

qatar127, why is this any of your business?

A group of people are organizing a trip to the desert. You are not invited. That's all that's going on.

I don't know if you're aware of this, but a lot of things happen that you are not invited to. Last night I saw a table of six women having dinner. Did they even tell you about it? I am going to a movie with two of my friends this weekend. Are you upset we didn't ask you what film you wanted to see? The family who lives next door to me is off to India for a week. I bet they didn't even buy you a ticket.

I really don't understand why this matters to you at all.
