I have a tumi man purse that I wear. Tried to stop it and went, pockets...god that was a nightmare. I like having a place to put things. One place. I am quick to lose things if they are separate.
A man bag is convenient. My wife on occasion says, "don't forget your purse". She is not joking, nor trying to hurt my feelings. She just sees it the way she sees it. Sometimes that annoys me, but not enough to stop using it.
"It's a bag, babe."
It's sad that your wife has to remind you to bring your purse. What is she going to say next? "don't forget to bring your pad."
