Sometimes people post things that I think are lovely, kind, or heartwarming and offer encouragement to people who are in need of it. That makes me like them. sometimes they post things which are cruel, hurtful, untrue and degrade each other, that makes me not like them. Sometimes I bother to answer, in which case that person then either finds I agree with them or not and that adds to their opinion ( good or bad) of me, and so it goes on. I must say that there are far more nice people than nasty ones on here though, but there is the occasional surprise with people.
