Okay so....recently moved into a new house. The neighbours are a young couple. The back garden fence is only waist height. We've spoken briefly just passing hellos and the usual, but now the girl who is 20 has befriended my 2 year old daughter. Whenever my girl is in the garden she comes out and talks over the fence to my girl, my daughter really likes her and now my looks for her when she goes out in the garden. The girls boyfriend has a son who comes once a fortnight, when he was here last week they was asking if they could come into our garden to play with my girls toys and to play football, i begrudgingly agreed and now she keeps trying to come into our garden by making comments to my child about coming in to play. She even posted a handwritten letter to us both apologising for not having come out when she said she would and saying that she will be there as a friend for my daughter. What the fuck do I do?
