I get that, I totally get it, a tough problem. I'm very protective of anything that moves which is mechanical, and I suppose it comes from knowing what it takes to create a machine, and to repair one if it's repairable. My older brother, who could build a house in two weeks and did, would borrow my tools and when I got them back they would all be beat to hell. Now I wouldn't have minded that so much but the house he built wasn't for me. Those experience along with the one Nivek describes has resulted in a complete Nazification policy of non~intervention and no can help you policy.
