I infer a lot about an individual's personality based on 2 seemingly minute details:
What's your favorite alcoholic drink? Not having one is also a valid answer.
(I was a bartender for a long time, and I can match drinks with personalities pretty well, and also get some insight as to what type of person you are based on your alcohol preferences.)
What kind of watch you wear. Not wearing a watch is also a valid answer.

Whatever you hatters be hattin. -Tay Prince
