<human>: I was at my aunt's house one weekend and she made some spicy Mexican dish for dinner that just didn't sit well. I went to let out a silent fart but ended up shitting myself at the dinner table. Completely embarrassed and not wanting anyone to know, I went to the closest bathroom and took off my underwear. I had no idea what to do with them because they wouldn't flush down the toilet and there was no window to throw them outside. So I ended up putting them inside a book and then shoved it underneath the sink. I was a young kid so yes that was my best plan at the time. I went back to the dinner table and we left later that evening. Three months later my mom gets a package in the mail with a note from my aunt that says, "I think these are *my name*" and sure enough I see my underwear, which were clean. So Reddit, anything you've ever done that you thought you got away with but didn't?

<bot>: I left my shit stained underwear in a book underneath the sink at my aunts house. Got them back three months later, cleaned.
