My child has a group of close friends at school. They are starting to want play dates after school or at the weekends. I work full time until half five or six and it's too much after school. On the odd occasion we have had one particular child round, he was really ungrateful and caused an unpleasant atmosphere in the house. My child loves playing with him and wants him round again. My child has been to his house for some playdates and it is our turn to reciprocate but I just don't like the energy and rudeness the child beings here. When he's with his parents he is fine and generally polite. How do I navigate this? I've hinted to his mum before about the odd bit of rudeness but she laughs.
