Dd goes to pre school, theres a dad that is friendly and chats to everyone, we say hello and as our dcs are friendly he asked a few weeks ago if we wanted to go on an outing at a weekend, i said i work every other weekend but he kept pushing for different days, the kids were both there and he was asking them and making it seem fun to them, and made me feel put on the spot so i said id let him know, few days later i saw him and told him i was busy and couldnt do a trip,i got called over by a nursery teacher so that cut the conversation short but he stood there waiting while i was talking to the teacher, he makes me feel really uncomfortable, hes always hovering about,i saw him drive past me and dd on the school run then must have gone around the block as he then drove past us again just in time to park up at the bottom of the road me and dd were on and then he walked to nursery with us and his dd from there even though i was on the phone, he does things like this all the time and its making me feel uncomfortable, what would you do
