I think most people expect you to say something positive or at least not negative, so it's usually fun when you go through the check out and the girl says, "Hi, how are you?" to then launch into just what sort of a shit day you've had and explain why your three year old will be lucky to see four, and how your teenagers are spawn of the devil, and your husband is a useless see you next tuesday sometimes and how the cats pissed on the mat AGAIN, and the dog keeps getting out even though the fence is fortified better than fort knox. [breath], and then you ask how the check out chick is and she looks at you like you're some kind of a crazy woman.
Yep, most people don't really care, so sometimes, it's good to make them realise that there's no point asking unless you really really want to know.
I hope things get better for you monster. It sux when something really goes wrong. xx
