I noticed at the weekend that the couple that live opposite us were carrying a baby into their house. We never really speak to them apart from the odd hello or wave from the car. I never even realised that they were expecting.
I popped a note through her door earlier to say the above and to congratulate them on their new addition to the family. I also mentioned that I was a FT mum and was home most of the time. If she would like a bit of adult conversation and a cuppa to give me a shout.
Not sure if I have done the right thing as I get the impression that they like to keep themselves to themselves.
