How Emily Plays Hide and Seek

I suppose this is based on the premise "If I can't see them they can't see me". It's possible that Emily gained these amazing skills at playing hide and seek from Rachel, who was hiding and seeking with Ben earlier in the day. Rachel hid under a blanket in the front room. Ben was standing right next to her so she decided to throw him off her scent by yelling "I'm upstairs Ben." Then when that didn't get rid of him she changed her mind and yelled "I'm in my room, Ben."
