Such is the proof (thanks be to one Daniel Laugharn for the link).
I went shoe shopping with my wife today after we both got out of work. She's getting close to the four month mark.
(Parenthetical: I had a bedtime conversation that after the baby is born me and the wife are going to get a baby sitter after eight or so months after or whatever, and we're going to get a friend to watch our kid or something and we're going to go out and get really drunk and then have really drunken [and possibly other things] sex. I kinda feel like we missed our opportunity for that. It's a strange feeling. Then again my wife's response to "Hey, you know what? I wanna take you out some night and get really drunk and have sex." was "You mean Fridays?" We'll both be here all week.)
So the shopping, Aili, was amazed. It took me four minutes to buy shoes. Literally. We went and got dinner afterwards (the wife has to have Zankou Chicken, like five nights a week. Seriously. She doesn't care if it's cold either, sometimes I have to grab some on the way home), and she was still flummoxed at the speed of light shopping.
"If I see what I want, I get it."
"What does that say about me?"
"Everything it needs to."
