I did not see what was said to you, but I am truly sorry for shitty people. This is what makes me very hesitant to reply to anything in communities - people like that. The thing is that to your face they would never be that way because they probably have a sad life without any happiness and probably have nothing going for them like you do. As you say and they need to make themselves feel better by putting others down and will latch onto something small that you may say and just run with it.
Personally I think that you are great and that is why I made you one of my friends - which says a lot for me since I only have 5 and only 2 of which reply to my posts from time to time. (Hmmm maybe I need to do something about that - heh)
Anyways Happy Mothers Day and take care.
