Moved house three weeks ago. We moved as we need more living space as a family and an extra toilet, but gave up fantastic neighbours and a nice road. We are only two minutes from our old house (great for us as there's so much locally we would never have given up for more space) and bought the only house we really wanted on our viewings.
Having said that, part of me feels a bit bereft for the old house, neighbours, road. I know I can still keep in touch with the neighbours - one lot I've seen properly twice and another one phoned me last week. Sounds silly, but I miss things like our conservatory, colour scheme of kitchen when we had it refitted, a decent integral cooker and the outlook. The new neighbours seem generally pleasant and have made a point of saying hello if I walk past their garden. Also, this really could be a house for life as it gives us what we need now, but can easily be lived in as we get older. I'm decorating my daughter's room next week and I guess as we start to buy new curtains etc, re-do the garden things will improve, but ...
