Recently 7 year old DC had a friend over for a few hours on a playdate. The way this friend talks to DC is pretty horrible, but i know i don't hear everything going on. They had a couple of big fall outs, the second time both were complaining to me about something the other had said or done at the same time. My patience had really been tested during the playdate, mainly with the way I heard the friend talking to DC, so I told them both off. Normally i wouldn't have told them off, I'd have been more patient. I didn't say anything when dad came to collect as i just didnt think, but since the playdate the parents have clearly been unhappy with me - ignoring me on the school run in the week before half term when previously they'd say hello and have a chat. I've texted a couple of times, just general chit-chat, as i normally would do, and havent received a reply which is unusual. DC is due to go on a playdate after school with this friend this week. Should I have said something? Is it really bad form to tell a child off when they are at your house (I did tell them both off so didn't single anyone out ).
