My father in law (fil) knows where we live! Several times we've invited fil over to ours to see the kids or for a meal or to watch the footie but he's always said "no" or "maybe" and not come
He rang up out fo the blue last night and asked if he could pop over! Well we had jsut got in and i was cooking leftover burgers from a BBQ so that was no problem. I told him it was nice to know he knew where we lived!
