Today when I wanted to shower, Scott was in ours and I didn't want to wait so I went to the kids' bathroom to shower in there. When I grabbed a towel to dry myself off I found a sucker stick stuck to it.
I don't know about your house but mostly at my house after the kids use a towel it ends up on their bedroom floors until I hound them enough to hang them up. and apparently this towel picked up something from one of their floors. (we still have a bit of Halloween candy and wrappers floating around)
I do wash towels, really I do. but maybe not regularly enough. I guess next time I shower in that bathroom I will grab a towel from the cupboard and not the rack.
