Bizman seems to be the quiet guy building things in his garage. While singing to himself.
I'd like to build things in my garage. Actually, during these almost two decades I've had the garage, I've built a box for firewood there. Probably singing to myself while doing it... Unfortunately my garage is not a good place to build anything: No electricity, no light, no heat. Remind you, in the winter -20 centigrade is nothing strange. But I have built things of inside my house, finding it very satisfying to see the results of my job. Especially because I'm not a trained carpenter, I have been educated to be an accountant and a PC support.
The funny thing is that although I seem to be introverted, during my over 3 decade work history I've always been a customer servant, meeting numerous people daily - and thinking that socializing is the best part of my job!
