Things to do on the school holidays?

I like stuff on the computer, especially dress up/designing games. ANYTHING. especially awesome minecraft seeds (u know u love it). I am a girl. I am young. I cant go any where, cause mums asleep and cant watch tv cause my bros playing playstation. Good sites or just plain good ideas needed. Even if it has nothing to do with the question, just answer and a sutible reward shall be given (5 stars) and needed quick. what did u do when u were young on the holidays? btw, its freezing so no 'outsides'
