Bored...
I showed my sister and she kept going "AAAAAAAAAAAAAAAAAAAAAAAAAAAWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWW"
Well they're not girly (they love PATD and FOB...) and he is very rough (on Saturday, I turned off all the lights upstairs and she was in a bad mood so when she came upstairs she asked why I had turned them off and since I was laying on the floor (don't ask) she then not only trod on me, but stood on me quite close to my heart -_- EVIL!) but you show her anything about baby animals or animals doing cute things, she'd just say that (plus sometimes "baba")
Both my sisters are 13...
