I stayed at a friend's house a few months ago and used her husband's shower. There was a squeegee hanging on a hook on one of the walls of the shower.

My first thought was, "What the hell is that?"

Then I remembered my dad telling me long ago that "normal families" wipe down the inside of the shower/tub after each family member finishes.

We never did that in my family.

I didn't want to be a bad guest, so I used the squeegee. I'm afraid I may have half-assed done it since it was all new to me.
