V- very true! None of my campers ever want to claim any dropped underwear, but they always (without fail!) forget some important article of clothing or a towel when they go to shower or change!
Same with socks! My campers will bring me a sock we find on a trail and want me to put it in the lost and found, as if the owner would even know they were missing a sock, let alone would be able to pick theirs out from all the others!
