What my "friends" did to us at dinner

So me and my roommate, Elaine, were planning on going to dinner and thought that maybe some of our friends from last year would like to see us again. I've been tired from being cooped up for so long that I thought it would be nice to see them again (even though they aren't my favorite people in the world, but they certainly aren't the worst). Until maybe now.

Elaine texted one of them to see if they wanted to go to dinner, and she replied that she already had plans. Which, I mean is understandable and all.

Well, we then decided to go to dinner a little later. And guess who we see? All of our "friends" sitting together. I know they saw me, and they know that I saw them. And they did nothing. I still haven't heard from them.
That really makes me think that they had something against me as well. I knew they didn't like Elaine, but all of the things that they say about her are totally wrong from how I see her.

I really wished that I would have gone up to their table and confronted them.
It really would have felt great.
I'm so upset at them.
I kept telling myself that I was going to make new friends this year, and they are certainly making it easy.
