My DH had a dog in college who would ride the bus from one campus to the other, somehow knew the time of day and DH's schedule to sit outside the right building (she would wait at different ones different times/days) to meet him each day. Everyone knew the dog that rode the bus (only some knew DH). The dog was featured in the yearbook--big picture. Very smart dog.

DH always credits the dog with attracting nice girlfriends
