SH: Hey! You changed out your toothbrush.
SH: It's blue. Now I can't tell which is mine [also blue] and which is yours.
Me: Just throw mine in the drawer. I need to get another one tomorrow anyhow. This one is too hard.
SH: I guess it's time for me to change toothbrushes, too. I've been using this one for a while.
Me: Just take mine.
SH: That's gross.
Me: I only used it once.
SH: But what if I catch something?
Me: Like conservatism?
SH: Yeah. That's what would scare me the most.
