Input: Text: today i cut my little brothers hair to 7mm all over his head. my other brother was like "cut my hair too but i want something special"... this means no good!

my brother wanted me to cut his hair with an electrical hair cutter. he wanted something like an undercut and so i tried to make his wish come true but i slipped with my hand and couldn't get the upper hair to be symmetrical again.
i tried to fix it but it got worse! 
after talking to him for about 10 minutes he decided to get the lower part of the undercut as short as the gap around the upper hair i messed up. 
his hair is now under 1mm and 18mm on the top and he doesn't want to get the 18mm to 3mm to make it look ok... 
to make it even worse he has to take photos for apprenticeship applications and is saying that he wants his hair to be like this and to not cut it shorter on the top... 
i felt so freaking bad that i gave my cap to him to cover his head. 
as i corrected the haircut i thought about "accidentally" cut a straigt line of 1mm hair length into the upper part all over his head to have to cut the rest as short as this mess but i couldn't get myself to do it.

 
i slipped while cutting my brothers hair and had to fix it. he now has an undercut with 18mm on the top and <1mm around the head as the lower part which makes him look like a nazi and he has to take photos for his apprenticeship applications and his future boss will see him like this because he doesn't want me to fix it again.
to be fair i wouldn't want myself too to fix the haircut..

TIFU by cutting my brothers hair...
