Welcome to the planet matey. I get that glazed look from the wife too however my kids seem genuinely interested which I'm not sure is a good or bad thing as they are only kids. Although I'd already had my first ciggy by the time I was their age.
Welcome, +1 for the glazed look here too, they think I'm a mad scientist with all my bottles, pipettes , bits and pieces, and shiny collection, now then where did I put that vegetable glycerine? ..............
