Do I deserve punishment I am getting for being mean to my sister?

yesterday i had a row with my older sister, because she is claustrophobic and hates confined spaces , i locked her in her room, i enjoyed watching her kick and screaming to be let out,i even recorded it on my phone, i only meant for her to be locked in for an hour or 2, while anyway my friend rang up and i got distracted and went out, i forgot about my sister, my parents came home 8 hours later and found her locked in, she had missed her driving lesson and a date with her boyfriend,she even had to wee in a flower pot, my parents went mad and said i would be getting a taste of my own medicine , they said i will be spending the next 3 days locked in my room as a punishment, this saturday is my cousins 16th birthday party and my uncle is taking me and my 2 sisters to a top theme park, my parents said i cant go as i will be locked in my room as a punishment, i was REALLY REALLY looking forward to the trip i dont want to be punished, i have only been locked up for 3 hours and already i hate this punishment advice please ?

Well Diz, yeah you do deserve a kick up ass for being mean to your big sis?? big sister?..geez... maybe your parents have done you a favour. either way, you gotta grow up & man up & cop it on the chin; you dish it? expect it back..simple as. Guess you're lucky they didn't take your phone or i'net, then you'd really be punished.

they have taken my phone and tv, i have my pc for school work reasons , i am not supposed to be on this site, the reason i have my pc is my parents have set me some essays to write, they want me to look up how claustrphobia effects te a 4 page essay on people and write a 4 page essay on the subject, i also have to write a 4 page essay on unacceptable behavour and punishments, i dont like this form of punishment so does it have to hurt so much ?

Personally, I think your parents should have put you in a smaller confined space and not your room. And there should have been no PC privileges.
