My husband, who is the sweetest guy, does that on occassion too.
Once, while at the corner deli, he ordered a bacon, egg and cheese sandwich for himself for breakfast and got 1/2 dozen bagels for my son and his weekend sleep-over friends ... he then turned to me and said, "You want something Babe?", to which I replied, "Yes!, I would LOVE a bacon, egg and cheese sandwich but I think I'll pass thank you". He just looked at me ... I could see the reality hit him and he felt SO BAD.
He didn't mean to be "mean", he was just being considerate, and we all know how forgetful guys can be! - sorry fellas
He also did that to me in a Quizno's the other day but as soon as he said it, he realized and almost died that he slipped again ...lol
As a matter of fact, my husband asked me why he always seems to put his foot in his mouth ...LOL... I told him he couldn't help it, that he was just 'wired' that way
I also understand your need to vent!
THAT'S WHY WE'RE HERE!!
