It is possible to tell things by a handshake. I like the "looking in the eye" syndrome. It conveys interest. I like the firm, though not bone crushing shake. The bone crusher is trying too hard to "macho it. " The clammy or diffident handshake fairly or unfairly get me off to a bad start with a person.
One morning I woke up and found my favorite pigeon, Julius, had died I was devastated and was gonna use his crate as my stickball bat to honor him. I left the crate on my stoop and went in to get something and I returned to see the sanitation man put the crate into the crusher. I rushed him and caught him flush on the temple with a titanic right hand he was out cold, convulsing on the floor like an infantile retard.
