Oh, when I used to visit my first shop, one wife said the differnce from boys and men are the price of their toys. I politely replied these are models. She replied, like model car kits.
I said well, no. Her husband then told her, like your $2,000 sewig machine. She then replied, which I can make things to sell if I wanted to.
This went on for a while. Another guy said that some do build layouts for customers at a high price. After they left, the owners commeneted that thery seemed to have an adversarial marriage.

Those without interest in this hobby don't understand what skills and creativity is necessary to build scenery, do the wiring and electronics and maintain the system. Also the modern computer knowledge to program route's.
