i wish i never drank coffee on an empty stomach that one time.. bad move.
nah, but i wish i never casually forgave my friend for treating me like garbage during middle school. we were best friends, then a new girl started attending our school, and they went and became best friends while i was left in the dust. my friend adopted a bad attitude to get along w the new girl, and at the end of the year, she apologized for treating me like garbage, but i just shrugged it off like "it's okay."
i know i was a child, but i wish i had been a little bit brighter and more willing to call her out for it.
