If you get up… one of the girls will still your spot. And, they are sneaky about it too!
To illustrate…
Sit at the computer… girl #1 will come up to you. Girl #2 will go indicate she wants something… cookie, cracker, something from the pantry. You get up to get *whatever* for girl #2 and girl #1 will get in your spot and grin from ear to ear knowing *exactly* what she did.
Illustration number two…
Sit on the couch. Girl #1 will cuddle up with you. Girl #2 will indicate she wants something “forcing” you to get up to get it. Girl #1 will QUICKLY steal your spot, the remote, the blankets and pillows and giggle incessently.
