WHY ARE PEOPLE SO WEIRD ON ADM?

I was outside the school (in game) waiting for tasks and I got traded. It was normal and stuff and she asked to offer for my fr ssbd. She put a no pot kangaroo and I said yes and accepted. I waited for like thirty seconds and she declined. After she traded me back and asked to do it for my fr turtle instead. I told her that it I didn’t want to so she said we can do the trade for my ssbd if I add. I said I’m not going to add because I don’t want the kangaroo so bad as to overpay for it and declined, SHE THEN TRADED ME AGAIN. CALLED ME IMMATURE AND TOLD ME NOT TO GET MAD AT HER FOR NOT WANTING TO TRADE ME FOR MY LOW VALUE PETS, SAID SHE WAS REPORTING ME FOR BULLYING THEN LEFT THE SERVER?
