Look before you leap.

Poor little River looks as though her short life just flashed before her eyes in the moments before Simon plowed right into her while leaping from the loveseat to the couch.

River:  I can't believe you ran into me!  Do you know how scary that was?!
Simon:  I said I was sorry.  I didn't mean to run you over like that.

Success!  And a lesson learned.
These pics were actually taken one right after the other.
Simon really did get on River's bad side for running into her--the "I'm sorry" look he gave her apparently wasn't enough, so she gave him the "bunny butt" and quickly hopped off of the couch to go into the kitchen (where she knew he couldn't follow).
Oh, bunny drama!
