Not for me
As we’re all no doubt aware, kids can be mean when they want to be. I’ve run into people I went to school with as an adult and had a blast with them, even when they were horrible to me when we were younger. I don’t really think we can forever be held responsible for our actions as children.
In this case, I think that still being angry at this girl for something that she didn’t even do is a bit petty. However, you’re under no obligation to hang out with people just because they want to, so she is quite within her rights to make her own choice.
