What you call my trains is not attached to my self worth in the least. However, insisting on telling other people that THEIR their stuff is toys and what it means to them, ANYTHING they own, is just rude. Whatever you want to call your own trains, toys, junk, squat, trifle, trinket, worthless, go for it. What works for one person does not work for another.
You guys keep on bringing up that somene has a great sportscar and that they call it a toy. That does not phase me in the least. The word toy is an individual value judgement, different for everybody, and not necessarily based on an amount of money something cost. A $100 train could be worth the world to someone, not paltry, trifling, trinket, or bauble. And before someone brings up the price of a sports car, some things are valuable for other reasons.
