well first....
Lenny:
My impression of regret.... i guess it would be only if i did an action to hurt someone and didnt mean to, so for example, one of the few ways to really peeve me off is lack of common sense.. so after an hour of explaining something over and over and the person asks me yet again, i snap and say something like " for !@#$ sakes, i just sat here and wasted and hour my my !@#$ing time for nothing, either you dont listen or your an idiot" then after i blurt i see them cry and think opps... but for me to actually swear it takes alot, and for me to take it out on others it takes alot cause i normally harm myself before another person, but i have been controlling this..

Rapunzel: they were obviously peeved, but i had great parents because no matter how mad or sad they were they only showed me happiness, they never understood why i could show so much anger or sadness for such a young child, they never tried to change me... that i can think of, my dad would usually just let my mom calm me down and talk to me and make me happy again...

Sannah: I think the first time i realized my parents had feelings was not until my LATE teens, It could be because i never saw them upset until then... and the first time i made my mom cry and saw it i guess kicked in.. now i am better but still have my days, but now i try to be more concious about her feelings. I guess i used to act the way i did and thought it was normal, cause everyone thought i was the most adorable sweet and innocent girl, until they got to know me lol.

hope that answered everything..
