My sister keeps telling me no more trains. I buy my nephew train sets for his birthday every year and find reasons between each birthday to buy him more just because. He has crates full of trains and tracks, depots and other buildings. Some remote controlled, some wooden, and some of collector’s quality. To him, they are all collector quality. He loves them and I try to respect her wishes and control my spending, but how can she not appreciate his love for his trains? My nephew’s father smiles at me conspiratorially when I say I will refrain from “just one more.”
