FINALLY
thank you for stating a genuine and understandable opinion
All of us have many different encounters when meeting people, so I can understand why you wouldn't be happy around him.
Just know that if somebody is not a person you like, you can state why you don't find them nice to other people, and that's a-ok. It's just that at that point you should really just stay away from them as much as you can, as this reduces any possible bad experiences you may have with them.
I respect this comment, I hope you find someone you enjoy being with, and I'm glad you're being honest while at least somewhat polite.
