Input: Text: so earlier today i was driving my brother and two of his friends to a mac demarco concert in dc. they are all pumped up for it but i have to find something to do for a few hours while they are in there. during the ride my brother pulls out a bag of cookies and we all have a few. we jam all the way down and i drop them off but don't know what to do and dc is kinda sketchy at night so i drove to my dad's place in edgewater for a bit and got some dinner. afterwards i had some time to kill so i picked up sweet frog for my girlfriend and headed over to surprise her since i haven't seen her in a few days. being all excited to see her she was the only thing on my mind and i was racing to her house. i roll up and go right to the door and was invited inside immediately. she was eating dinner with her dad and asked me to sit with them. not even a minute after sifting down and starting to talk to her dad it hits me in the face like a bus. i was so confused trying to keep up conversations with my girlfriend and her dad, i was so high i couldn't comprehend a word from either of them. i sat in this chair trying to find a reason to have to go but i was in such an utter mind fuck from trying to talk to her i couldn't think of a way, i was trapped. helpless i fight through 15 long minutes until her mom came home. i was doomed, she would totally tell i'm stoned i can't believe her dad doesn't already know! the second she sees me she asks me to leave because she thought it was getting late, finally a reason to leave, i rush to the door say my goodbyes and get the fuck out of there as fast as i could. now i'm about to drive back to dc to pick up my brother and his friends, head home for the night and hope for the best.

TIFU: By forgetting I ate a couple of cookies
