Input: Text: okay so this is my first ever post (yay go me) and it actually happened today.

i decided to go get my guitar fixed; now considering i don't have much of a musical life outside my room i like to show it off whenever i can. but today was a nothing day, i wasn't going out, having anyone over, nothing. so we drive to the shop and i'm carrying it without the case so everyone (the girls) can see. i'm taking side glances around and awesomely they're all looking at me, smiling. i feel great. *in walks the fu* i pull open the door for the shop and greated by the usual guy there, but no the usual matter.

"bit tired today are we?" he asks with a smirk.

i look down at myself and it hits me, congradufuckinglations j you forgot to change out of your pajamas.

i did the only thing reasonable and laughed  it off, no harm done.
oh boyo was i wrong. walking back out past the girls, this time realising what i'm wearing. the girls then begin to fake sleep and act tired and laugh.

it's not a terrible fu but i will no doubt being seeing those girls around and i doubt they'll forget me any time soon

 
update - my dad knew the whole time and pruposly didn't say anything #fatheroftheyear
update - i have seen those girls over the past few days and no, they havn't forgotten...
