bumped into daddy's rock

another black eye. surprise. micah found one of our landscaping stones outside the fence so he picked it up to walk it back into the yard. emmit followed. micah stopped;  emmit didn't and he ran into micah (actually the rock that micah was holding in his hand). viola. now, how come when this happens ET tells everyone that he "bumped into daddy's rock"... when I turned around to walk down the stairs and didn't know ET was behind me, and takes a tumble, he tells everyone "mommy pushed me down the stairs" ?!??
