With everyday on the same route, you have your commute down to a T. You know exactly which side of the subway is going to open to let you out, or which time in the morning you need to not get stuck in traffic.

Almost every day is identical, so much so that each commute is barely distinguishable from one another.

But it just takes an unexpected conversation with a stranger, or your favorite song coming on the car radio to help you start the day off with a smile.
