Mmm hmm. I often wish I could come out on top with these people. Out play them. But it's impossible to stoop to their level as they have experience.
I think the times when I feel best is when I tell them that although their actions may not be intentional (pfft), they are hurtful and I have too much respect for others and myself to recognize or participate. Then when they say something stupid again, I just give them the :/ look and shake my head. No words. If pushed, I just reply I would rather not promote that kind of attitude. Effem.
But normally, I don't have the guts. More often then that (than?? Can't recall, don't care to...lol), I'll give the :/ look and shake my head with no reply. After a few times I'll get questioned on my response and at that time I'll let em know. We're all human. There's no need to promote ourselves through the demotion of others.
