I remember back in the day (just did that to see who I could piss off) I heard people say "Have a nice day" to which some would retort "Don't tell me what kind of day to have."
I find that incredibly rude. They are just saying something nice, at least something not hateful...it's not really different than "goodbye" or "see you."
Many times people just don't know what to say. I have told people things will get better
because what they are going through really sucks. And eventually things will get better for most of us. I guess it's better than a kick in the cunt, an "it sucks to be you" or "yeah, you've had bad shit karma coming for a long time, asshat."
I think it's sad when people are judged for just trying to say something nice, even it you don't feel it's appropriate to your situation. Remember, not everyone is uber-intelligent (who'd that piss off) like Dwellars, and if we lose those polite though trite sayings we might as well just all grumble, snort, and walk away when someone tells us something is going wrong for them and we can't possibly understand that situation.
Just my two cents, for whatever it's worth, because it is what it is and at, like, the end of the day there's always a rainbow...
oh, and @ Razz...I hate it when someone uses "whenever" for "when." It sounds like they're talking about some event that occurs multiple times. That is grammatically incorrect, not a harp on people just trying to be nice.
