Well obviously if you can ask a question on here then you must be able to play games on what ever devise you have with you right now. Just keep the volume off and play games all night. Or the more boring option... Do homework or read or stare at the ceiling like your dead. Or you could pretend your a monkey... that's always fun to do no matter what mood you are in.
Draw,dream,think,laugh,ENJOY YOURSELF!!!!! If ur grounded obviously u did domething wrong to piss ur parents off :/ but don't be suck a downer about it or stress I always do that and it doesn't help...why not be happy ur young think of things u wanna do as you grow,laugh at funny moments in the past,dream about all the impossible things that will never happen but as u dream make them happen,draw random things or something u see happening,be great full for all u Have and think of what you'll do next! How this helps buddy :) P.S. stay out of trouble -AlexisJadeLuvv <3
