Suspicious mind ?

I wouldn't say I'm an overly suspicious person, but:

I'm suspicious of business people I see on the subway who aren't carrying a bag.  As a corollary, I'm even more suspicious of people in airports with no luggage.

I'm suspicious of people I know in my urban neighbourhood who I never see walking anywhere.

And as my Facebook profile says (somewhere, in answer to religion) - I'm suspicious of coincidence.  See related posts on this if you interested here.
