Input: Text: this happened a few weeks ago.  
i was visiting my brother down south in birmingham, had a great time but needed to go home.   
so i'm waiting for my coach and i'm listening to a song i made on my phone when all of a sudden i have this great idea. i thought that if i rubbed my fingertips off something rough they would grow back stronger and then my fingers wouldnt hurt as much playing guitar. so i started rubbing them off a rough wall outside.   
then it was time to get my coach. i confidently pull out my phone to get my booking confirmation but my phone wont unlock...... the fingerprint recognition isnt recognising my fingers...... because i've fucking shaved them off..... and i cant remember my backup password.     
the driver says i can go to the reception and get help. so i ask for help and they say i can use the computers to check my emails but by the time i got the email the bus had left..... and that was the last bus. 
so i had to call my brother (from a payphone) and explain that i would be staying a little longer.......  
he laughed. a lot. and then had to call my work and explain how i wouldnt be in work tomorow as well and then buy a new coach ticket for the next day....

TIFU by trying to improve my guitar playing.
