on being siblings

anything zoe does/has/sees/touches, dominic has to do/have/see/touch.  

you can convince him to do just about anything if "zoe's going to do it too!"

he wants so badly to play with her but he has not yet learned gentleness and she has learned to be a bit wary of him (look at the concern in her eyes!)

but he can make her laugh more than anyone else.  and occasionally, he does something -- like barreling into her on the couch -- that totally freaks me out, and she loves it!
