For most of my life I've lived in a traditional nuclear family set up, so whenever new neighbours have arrived I'd have said "Hi welcome to the neighbourhood, I'm Jane, DH is Chris and the boys are John and Peter".
Now I am widowed (for a few years) and I have one adult son left at home, plus a BF who is here quite often.
So, if I'm introducing the residents it's me, a widow and DS2, but they'll see BF coming and going...
I don't need to be told I'm over thinking, I'm not really, it just occurred to me it will be different this time.
