pajama games

This "mine" game is getting out of hand. Connie and Gusty have been playing a game where Gusty pretends to take Connie's pajama's and says "mine". Now she steals my pajamas too! Interestingly, she knows which pajamas to steal. When she stole my pajamas and I pretended that I wasn't interested, she offered them up "want this? want this?" As soon as I said I did, she once again claimed them as hers "mine! mine!". When we got into an impasse, both of us tugging on them, she suddenly stopped and looked into the distance. I turned to see what she was looking at. Before I knew it she'd tugged the pajamas back into her possession.
