Bullied by my sister?

Older than you? I thought you guys were twins? Maybe older by however minutes, but that doesn't count. When you are home alone, record her. But don't let her know that you are. Then show your dad. I can't believe I am saying this but...stand up for yourself. Scream at her, scare the living $h!* out of her. Punch her back. Do anything so that she will stop. Go to a friends house until your dad gets back, or until she stops being such a jerk. Good Luck [:
