Alvin Workin' on the Railroad

Silas bombarded me with some interesting questions today... "Why does Alvin work on the railroad?", "How does he stay safe?", "How does he move the tracks?". I was caught completely off guard. I really didn't have answers for him. I asked him what cartoon he saw that on - no cartoons. I asked if they read him a book about that at preschool - nope. Did he mean Alvin and the chipmonks - ummm NO. I didn't know what to tell him. About 10 min. later he asked me, "Mom, what's the next words in the song?". I asked him what song. He said, "You know, 'Alvin workin' on the railroad, all the live long day'". OHHHHHHHH It all fianlly made sense!
