My lovely friend has a ds same age as ds1. He's a horrible child (6yo) and has been since I've known him - mean, aggressive, competitive. The parents are lovely and hospitable, and take the lo to task for his behaviour (with no effect at all) but I feel we can't see them as a family as I can't inflict it on ds. It's really torture for him. What to do? I can't say the truth - it would be too offensive, but I'm always making excuses and feel horrible.
