OMG, I'm so paranoid now. I need to get some locks for both of the rooms I keep my stuff in. I too, who have only done models here and there over the years, but have now decided to make it a full time hobby, have my own horror story...
Once upon a time, back when I was about 12-14, I built Darth Vader's Tie Fighter. It was the first model I really completed that I could call perfect. There were some flaws, but compared to my other stuff I did, this was the Mona Lisa. I was so proud of it; I hung it from my ceiling for the world to marvel over. DUM DUM DUMMMMM! You see where this is going. Well one night just as I was turning into bed, my mom came in to get my dirty clothes to wash.
"Oh, I haven't seen that before. Wow you did a really good job Brad", she said.
Then she touched it. A solar panel wing, which had been firmly attached there for days, had magically come undone from the unknown destructive properties in her touch. Off came the wing, down came the fighter. Must have scared the hell out of Darth Vader #:-) I screamed bloody murder. I never wanna hear that sound again. It was the sound of my heart being crushed to death.
"Don't worry, you can always glue it back", she said so care free.
I wanted to cry, I wanted to scream, I couldn't sleep that entire night. I love my mom more than anyone else in the world, but that moment, I wish I could disown her. The worse part (besides the model breaking) is I had to go to school the next day

When I got home, FROM HELL, I cleared off the dining table of her sewing junk (yes, she sews; too bad you can’t drop a shirt and have it shatter into a million pieces) and went to work fixing my model. I tried my darnedest, but sometimes you just lose a few. Nothing could be done. There were cracks in the plastic. Some parts broke clean off. Other parts were bent. It was horrible beyond belief. Doctors have to face losing patience. I had to face losing a model. That was years ago, and I still have that horrible memory burned on my head. I think about it every time I build a model. The best thing to do is make the best out of a bad situation. Learn from history. If I were you, I’d post pics of your devastated models. It's too late for your models, but it may not be too late for someone else's. Post it as a warning. If one model is saved because of it, then at least it will have been broken for at least one good reason. Lock the doors people. Children, pets, friends, family, and any other living thing that never build models are like "model sappers". They're whole existence in your life is to destroy your models. They might not realize it because they aren't in the modeling "zone" you are, but that's what they do. They're the anti-modelers, so beware. Even other modelers can be dangerous. Trust nobody with your own models.
