Im probably gonna rustle some jimmies and get some flack for this, but here goes.
Sugar can be SUPER annoying, any time she joined an RP server I frequent she kept failRPing, as well as interrupting current rps so she could beg my friend to drive her places. She also keeps bugging me to pick her up and drive her places while Im building. It got to the point where whenever sugar would join i would stop playing and do something else. Now I sympathize with yawa, he just wants to be left alone in peace, and not have to be practically forced to be friends with someone.
Im not saying sugar is a horrible person, but I feel like shes made out to be some kind of angel, which she is not. I dont like what op said either, neither do I condone bullying people with mental disabilities. All I am saying is that sugar can get on your nerves and that I can see why some are annoyed by her behavior.
