The Joys of Siblings

This morning, in bed, soon after waking up, Sylvia, totally unprovoked, pushed Erik out of bed.
I said 'Sylvia!!! Don't push Erik out of bed.'
She replied 'He was being MEAN to me!'
Me 'Um... He wasn't!'
Sylvia 'Yes, he WAS!'
Erik climbs back into bed and Sylvia drops herself off the side of the bed. 'Erik is pushing me!!!'
Me 'No, he isn't!'
Sylvia, climbing back in 'Yes, he IS!'
Proceeding to fall out again 'See!!! He is pushing me!!!'

Um... She is really playing around with this social interaction stuff :D
Later today, she was mad at him for something and declared 'Him is NOT my brother!' I don't think that's how it works, dear :)
