you make sure you have your U-lock with you at all times "just in case"
you carry a spare tube on the train
when you get the day off, you are disappointed because now you don't get to commute
you want a fixed gear EVERYTHING
you debate true-ing wheelchair wheels
you get uncomfortable in cars
you get to the grocery store right off the bike and are still in tactical mode....weave between shopping carts, etc (I do this all the time)
