SH: The crummy underwear is for traveling because they fold up small. The nicer ones are for at home because I wear them longer.
Me: I didn't know you had a system for your underwear.*
SH: Of course I have a system. There's a system for most things in the mind of an engineer. But there's not a system for jeans. Wait. I have a pair for traveling. And if I go out, I wear whichever ones I've already worn to the bar. So I guess I do have a system.
* I have a system for my underwear, of course, but I didn't think SH had any reason to have a system. He's a guy. He does not face the same issues I do, such as which underwear shows a panty line in my gym clothes?
