I was odd in that I (no doubt influence by my parents 'helping') kept all my Lego separated by colour.
Huge big plastic tubs, full of all kinds of random Lego, dog hair, half eaten biscuits, star wars figure weapons and broken bits of transformer FTW!
NOOOOOOO!!! You are the freak! How can you treat Lego in that way!? I'm almost having a panic attack thinking about it...omg...omg...
My Lego was separated by colour, of course, and I had a big bucket full of various 'specials' and another with Technic stuff in it. No-one was allowed to touch my Lego. I had a tiny bedroom and my mum always used to get sick and tired of standing all over it to get in to my room so one day, after threatening to throw it in the bin if I didn't clear it up, I came home to find my floor bereft of Lego....This episode surely scarred me for life. She had actually only hidden it in a bin bag under the stairs but I have never felt so gut wrenchingly sick in all my life as I did that day.
I bought myself a Technic bulldozer a few months ago, it's ace. I want more! I have 2 boys and the eldest barely looks at the Lego I've bought them, the youngest goes through fazes of playing with it, mostly to make robots, guns and cars but nothing like I used to, whole weekends used to be lost to creating fortresses, towns, fairgrounds, space ships...everything had to have 'secret' rooms, compartments and entrances....argh, I want to buy a huge box of Lego now!!
