<human>: Summarize the given text in a few sentences.

TIFU. I have two pairs of the same shorts because one wore out and has holes; I haven't thrown them out yet because as mention, I'm a fuckup. Sunday I went to a rockclimbing place and took one of these pairs with me, believing it was the good one.

Today my mom is taking some stuff down to the laundry room and she holds up the shorts I had worn and says, "why are the ones with holes here? Didn't you throw them out?" I instantly realized I'd worn shorts with holes all through the crotch area rockclimbing and somehow hadn't noticed.
<bot>: mixed up old shorts full of holes with their replacement shorts and went rockclimbing with a bunch of holes in my shorts.
