I am not a night owl. In fact, I am very much a morning person ... actually, I can go full speed through most of the day as long as I get my night of sleep. My husband, on the other hand is a night owl ( this picture is in his honor :) and drags into the bedroom long after I have fallen asleep. This works well for us considering that we are retired and would be in each others face all day if we kept to same hours. This way I have my mornings to myself, he gets up late and we share the rest of the day (if I am home, that is) and then he has his late evenings to himself. I highly recommend this routine ... it keeps the peace, so to speak.
