That phrase drives me nuts. Why, yes, it is nice, thank you for sarcastically and passively aggressively noticing. Why do people say that? Do they really want you to feel bad about having a good time and/or enjoying something? That's exactly how it makes me feel and I hate it. Or is it that they just want to draw attention to their own woes? "Oh, it must be nice that you got to sit at home tonight and watch TV while I was at work grueling away." Well, yes, yes it was nice. I don't know if the intent is there to make you feel bad about being happy, but it sure as heck happens. I think it really is driven by self-centeredness.
It first I use to ground out a "It was." I then decided that I would take the comment at face value and not let it bring me down. Now I smile and confirm enthusiastically that it was, indeed, nice. I thought this would help me get past it, and for the most part it did. Then I saw that he commented on someone else's post on Facebook that "It must be nice". The way the reflected on him made me ashamed. I cringe at what people must be thinking of him when I know he's not like that usually (just in comments like "It must be nice").
Has anybody else encountered this and what have you done?
