Can't we share?

The other day we were at Office Max to look at copiers and also to copy some math worksheets for Noah. I was standing at the copier while Doug was watching the littl'uns. I guess Claire was bored or tired or both, because she started sucking her thumb and rubbing her neck. Chloe saw her doing this and decided that Sister looked like she was having a lot of fun. So she came over and tried to rub Claire's neck, too. But Claire swatted her hand away as if to say, "No way, it's mine! Get your own neck."
