Just like Chicamarun, our home phone is our business phone. If I don't answer it, we could lose business. If friends or family call while we are doing school, I tell them we are doing school and ask if it is okay for me to call back later. If we are having lunch break or something, I tell them I can talk for a few minutes because we are on break. When break is over, I tell them I must go. Friends and family seem to appreciate me being upfront. Very few people just drop by. If they do, we drop what we are doing and spend time with them.
