My aunt and cousin are sharing the exact same pair of shorts

I was at a Goodwill the other day and my girlfriend saw something weird, she pointed out a pair of shorts. I go over and take a look and it was so dirty it had white stains on them. Then there was my aunt and cousin wearing the same exact shorts sharing them. They were next to each other. I seen them and shook my head and was like that’s weird and then the lady leaves and my cousin stays there for 10 Goodwill minutes. There were no changing rooms in that store. My girlfriend didn’t believe me til we got home and i showed her a picture of a subreddit i added as a comment for proof. She went from not believing me to being skeptical about the whole universe.
