so i'm the leader of a science club at my school and yesterday we had a competition at a nearby university. so we go there and go about our day competing until finally we get to lunchtime. the university café was a little lacking (or maybe we just had high standards.) however, we only had an hour until our next event. throwing caution to the wind, i and two of my friends decided to walk to a pizza place that was just off campus, about 3/4 of a mile away. one of these friends (we'll call him joe) was with me in the event after lunch and the other friend (nick) didn't have an event. this becomes important later. we get to the pizza place and order. it took a little longer than expected so we had to get it to-go. we get our pizza and head back to campus (another 3/4 mile.) we get back to our team room, and joe and i ate quickly and got ready to leave for our event. we now had only 3 minutes to get to the room so we needed to get moving. and here, reddit, is where the fuckup happens. i realize that in my haste i had _left my bag in the fucking pizza place_. luckily i didn't need it for that event, but it had a lot of important stuff that i couldn't just leave behind. as i'm panicking, my good friend nick chimes in and tells me that he'd go get it for me as he didn't have an event. long story short, i come out of my event and he had my bag waiting for me. i felt terrible for making my friend walk 1.5 miles just to cover my mistake.

TIFU by being mentally inept.
