My grandfather used to fall asleep on his living room couch, which made life difficult for us kids when we visited -- since there was no basement in their house and little to do outside. We were told to keep very quiet, which was a challenge. Gramps had a nasty temper and wasn't a kid-friendly guy. Any sudden noise would make him jump up and holler, and when he hollered, he roared. This we quite enjoyed. The above scenario comes with a smile, from my past.
