Well I say hi and bye and make small talk with all my neighbours and as I respect them and I do what I like within reason. With working in the same place as you bring up your child may cause neighbours to wonder more than they should. It shouldn't be an issue but where children are involved it can be and worst comes to worst, it will be. I would rather risk working from a hotel or in a room than get social services involved.No offence to you or anyone else but I would not want social services to intrude in my life if I could avoid it.
