You are their little sister/brother! You actually have talent unlike them who have a secret you have yet to discover.. you don't go to huge events like their shows. You found them boring but when they were gone you took advantage of it.

Since you were the favourite child, you could get anyway with anything. Example, broke a glass. Blame it on a twin. Broke something else, blame it on the other twin.

You were singing in the shower and didn't realise they were home. Your voice is amazing!
