I'm sure this is a common problem but would welcome some sagely advice.
DD (10) was asked to a 'friends' house for tea. She knows the girl as a school chum and nothing more, and we agreed to this.
When I went to collect her I was greeted by a large Alsatian, the house was a tip with dog mess all over the garden, the stench of nicotine was everywhere and, I discovered later from DD, the father was quite abusive to his kids, openly swearing at them infront of DD.
The inevitable return visit is now being asked for by DD but we are extremely reluctant for DD to get involved with these arrangements.
How should we proceed: Just say no? Agree that her friend can come to ours but not allow visits to her friends house?
It's all a bit awkward.
Thanks
