From the moment he gets up to the time he goes to sleep this man whistles. It’s driving me “crazy” and I can tolerate everything else but his whistling. He also interrupts my conversations with my husband from time to time. How can my husband address these issues since I really don’t feel comfortable doing it. I’m not too close to my father-in-law and don’t know him well. From what I have observed in the last 3 months he’s lived with us he's kind of a loner and not very social. Keeps to himself in his own room.
