I think that sometimes mean people can eventually be nicer that nice people. Not always, but sometimes nice people just pretend to be nice and mean people are taugh, but it can as well turn in to positive. I had so many experiences where I eventually got along very well with mean people, perhaps because they were honest. And didn’t get along with nice people because eventually I found out they were fake.
Well you have to be careful with people that wear fake emotions on the surface. I definitely know what you mean though........sometimes a person that appears mean is actually just jaded and actually is a good person on the inside.
