"A gentle giant," right? Ne zot, I hate that phrase. It means someone who is laughing while he imposes on others using his size.
The brother of a friend of mine believes he must have precisely 8 hours sleep each night and demands that everyone in the house make absolutely no noise after he goes to bed. He becomes enraged if he can hear any sound at all from anyone else in the house. Needless to say. He has lived alone for many years and his girlfriends never lasted very long. Noises not attributed to people he can reach don’t bother him. He sleeps through thunderstorms and low flying jets.
