Lol. Too cute, my guys do this to me all the time. As soon as I get up one of them will jump up on my spot, and good luck trying to move them over when you come back.
Brutus does this every time also. We play the "I'm gonna squish you" game. Brutus will sit there like I cannot see him an I sit down in front of him and lean back telling him "I'm squishing you"! He loves it and goes crazy.
