My wife is the one that pushes me to get work done on the layout.
She says that she was attracted by the miniaturization when she first visited my apartment. She named the railroad.
She has also made some scenery, (trees in the early days) and made about 40' of back scenery last month. She also picks out buildings for me to make.
She also found time to work with the local Symphony Orchestra, is active in the Horticultural society, tries all sorts of decorative crafts, now concentrating on needlepoint, reads, and spends an hour or so per day with her mother in the nursing home.
The only real interference in the railroad is when she asks me "Is that new purchase going to fit in with the rest of your stuff?"
Oh, and when she wants me to make a continuous run so that she can hear the trains go!
