Betty is playing with the purple ball, Dolly wants it. Betty won't give it to her because it's 'her turn' and so Dolly gets angry and yells. I try to persuade Betty to give Dolly a little go, just to get some peace, but Betty gets upset and says 'but I've only had it for a second'. Dolly is still yelling.
Dolly is playing with the drum, Betty wants it. Dolly is having a lovely time with it, but Betty is adament that she needs to play with it. I tell her to wait her turn. Betty tries to grab the drum anyway which makes Dolly yell. I pull Betty off Dolly and tell her off. Betty gets upset, and Dolly is still angry.
Dolly messes with Betty's Happyland fairground arrangment, Betty gets upset. Betty messes with Dolly's two Happyland plastic dogs, and Dolly yells.
And so on, about 200 times a day, every day.
