Being left out

So, I hate being left out. I think I have some kind of complex about it from being left out as a kid. (In Middle School, the teachers always announced the summer birthdays during the last week of school, and they always forgot me, even when I reminded them, they still forgot . . . Oh, woe is me!). Today, I gave a presentation with four very good presenters and they were so good that we ran out of time before I got to give my part. Honestly, I felt that my point was important. It wasn't fair, and then I revisited all of the times that I'd been left out before in my life and was bitter for a while. I think that in my life, I will make sure that I don't leave people out. It is an unpleasant feeling.
