photo found here - this is not my sister (:
once upon a time my sister wanted/needed a haircut. my mom, being too busy, told her to have me do it. i was reluctant. i had cut my own hair (straight across, taking forever to get it even) a few times, but that was it. being forced into it, i started. i started at one side (her left, i think) and made my way around to the front right. by the time i got there, it was too late to stop what had been a gradual increase that turned not so gradual by the end. when i saw what i had done i couldn't hide the horrified look on my face. thinking i was joking, she asked, 'what?' i grabbed one side of her hair showing her the length, then grabbed the shorter end. she cried. i cried. we were both upset. my mom ended up fixing it. she got a lot of compliments on that short haircut.
i have cut her hair since then (not for years now, but thankfully all our experiences were better than that one) and so obviously she has forgiven me.
don't know why i thought of that just now.
