Faithful

Adonese is returning home from seeing the woman he is courting, and he is driving around a corner when his car accidentally brushes against the tramp 'Faithful' and knocks him over. Feeling sorry for him, Adonese helps him up and buys him a new suit of clothes. The naively innocent Faithful reads too much into this gesture, and he begins to follow his benefactor everywhere, expecting to receive future gifts. (imdb)
