I would have to agree with Nod. Humor gets me every time. Two of the guys I have cared for most in my life were guys who told me off when I didn't pay them the attention they thought they were due in a not very subtle kinda way (one actually flipped me off). I thought it was hysterical, started laughing and I will probably love him forever.
I love it when a guy gives me that "I will not be taking any crap from you young lady" attitude. (Can I say "crap" here??? dunno..anyway...) Not in a bad boy kinda way, but in an "I have too much respect for myself to let you treat me badly" kinda way. I have a lot of respect for folks who respect themselves.
