How common is it in France for people to keep the same telephone numbers when they move to a nearby town? I’m planning on trying to reach some French friends I haven’t spoken to in a few years, and since they now have 2 kids, I somehow doubt they are still living in the small 1-bedroom apartment they were about to move into when I last saw them right before their wedding. I’ve got his parents’ home number (if they haven’t moved), and I’ve got the main number for the family business, but given how rusty my spoken French is at this point, I’d rather not have to go into long explanations, particularly to receptionists who will have no clue who I am. I did some Google searching and found a listing with his first and last names in the town her parents are from, but even though it isn’t a terribly common last name, I’d prefer not to make a complete fool of myself to a total stranger if it turns out not to be them.
Also, what is the idiomatic phrase for “Is this the _______ family residence?”
