SH: Will we be able to do laundry on the trip?
Me: Probably when we get to Megan and Steve's.
SH: So do I need ten pair of underwear?
Me: No. You can always wash underwear in the sink.
SH: Is that what you're going to do?
SH: So I can pack less underwear.
Me: If you're going to wash it in the sink, yes.
SH: You mean you won't wash my underwear for me?
Me: Why can't you do it yourself?
SH: Because I'm a guy and we don't wash things in the sink.
Me: Then I guess you need ten pair.
SH: But why won't you wash mine if you're washing yours?
Me: Washing underwear is kind of personal, don't you think?
