Nicole and I were in Barnes and Noble last night doing some Christmas shopping.  We were standing at the main entrance which is an open area with a few displays of holiday-oriented books. After standing in the open area for a few seconds, I did something I never imagined I'd do:  I instinctively walked behind one of the taller displays so that it was between me and the main entrance and provided cover. 

I really don't think I play Halo 2 THAT much, but this is just weird.  I mean, in real life am I going to start looking over my shoulder, listening for the “ping-ping-ping” of a thrown grenade, and pausing beside doorways before walking through them?  I don't think it will ever come to that.  I hope.

I guess it could be worse.  I could be looking for blinking question marks in the ceiling, mushrooms to squash, or collecting flashing coins in mid-air.
