Susie had a toy panda that she clearly loved—she carried it everywhere and seemingly couldn’t be happy without it. She would smell it, rub her cheeks against it, and enjoy the sensation of feeling its fur with her fingers. But what she never did, Lorna noticed, was to play games in which she pretended that the panda was a real bear. She also had a little tea set that Lorna had given her, and she would occasionally stage imaginary tea parties, but she never invited other children. She always sipped her imaginary tea alone.
