I'm the same way, especially with my boyfriend. I pretty much just ignore everyone else if I'm in a pissy mood -- But it is the curse of my boyfriend that he adores me & enforces reaction. Try to do a good thing & you get **** all for it. :P

I don't worry too much about being that way with kids, though... Not sure why. I'd do my best to educate my kids & enforce strict discipline so if I ever DO lose my cool, they wouldn't feel to blame for it. My Mum's bipolar freakouts were enough to engrain that into my head, lol
