Yeah, get Left 4 dead 2 now before the 6th, you keep it forever.
Sometimes when you're driving down a road, a bug hits your windshield. It's ugly and unpleasant, but you just activate the wipers / cleaning fluid and it's gone in a few seconds. It's just part of driving down the road. You don't dwell on it, because that'd be silly. Bugs aren't worth the time.
