My wife is similar to yours - sort of... Every single restaurant we go to - if we've been there before - I know what I'm going to order before we ever walk through the door.. My wife always has no clue.. Like yours she will send the waitress away 3-4 times.. as soon as the waitress walks away, she stops looking at the menu and continues to eat bread or crackers or chips or whatever filler materials the restaurant is offering.. until the waitress comes back - then she sends her off again..
Now, the thing that NEVER changes that drives me batty.. She'll finally make a decision about what she wants.. and then leave the menu open in front of her.. She hasn't quite figured out that after sending a waitress off 3-4 times, that waitress is NOT going to come back until she sees my wife's menu closed.. so, after ten minutes my wife will wonder why the waitress has forgotten us.. So, for the 100000th time I'll tell her to close her menu.. she does, the waitress comes over and takes our order..
That scenario plays out every time we go out to eat.. If I never ever told her to close her menu we'd probably both be skinny as rails...
Friendship is like peeing your pants.. Everybody can see it, but only you can feel the warmth..
