If "new light" is not something in the house-wares department.

If "tract" has nothing to do with land or farming.
  
If you know where Nisan 14 of the Jewish Calendar lands on the Gregorian calendar from year to year, and yet you commonly forget your own birthday.
  
If for you, "Memorial Day" isn't in May.
  
If you spent days at a baseball stadium, never saw a ball and didn't even have a beer.

If you know the cleanliness of every coffee shop for four towns around.
  
If you think 2-door vehicles aren't really cars.
  
If you go to Home Depot and go down the aisle where doors are displayed, and you feel compelled to knock on them.

If you realize things are getting worse and you're thrilled.
