Some people are very lucky I'm not as petty as I could be.
Did someone do something that upset you?
Yeah, but I'm just gonna let it go. No sense getting worked up about it.
That's a good attitude to have. If you let bygones be bygones, it will just make things easier for everyone involved.
I agree, but I do wish people were nicer to me.
People should be nice, especially since it seems like you are a friendly person to others. If the people you hang out with now are unfriendly, you should consider looking for new friends. I'm sure there are people who would be happy to have you as a friend.
