moving truck

my car was behind a large white box truck on the arterial after work. I didn't pay much attention to it; on its back was pasted some lopsided signs and its sides were covered in graffitti. At the next stop light one of the signs - the lower, more crooked one - caught my eye; at the top it said "Moving for the needy - load your own truck" then a phone number, then "God love you." I followed the truck until the next red light, which it ran, leaving me at the front of the line of cars.
