I've always tried to mind my own business, afterall, to each his own isn't it? Besides everyone is entitled to their opinion as long as you don't trample on others along the way while making your point. To be at this stage yet making insensitive remarks, no respect for others is somewhat sorry.
There could have been a series of comeback but then again, what for? I'm only just constantly amazed by the things people would do and say just to feel validated and secure. Flabbergasted is a better word. Oh just move on already.
