Time to sharpen your party crashing skills. Go to an A.A. class and gather up all of the grimiest looking creatures then show up uninvited with a gift of extremely smelly cheese.

I would speak to one of them about why you were not invited. It could be a simple communication error or they might just dislike you.

It's crap when people do that to someone. Next to you want to go out invite other people and ignore the ones that didn't invite you. Show then how it feels.

They'll warm up to you eventually.

And thats why I don't talk much because stuff like this happens an awful lot.

well make your own group with new friends maybe.;)

Awh.

What jerks. I'm sorry. Maybe they saved you from their company. Payback time though.

How about you construct a plan and invite them maybe they will return the favor...

Ouch.
