I do all of the work on my cars, because I do it better than the "professional" shops. I restructured and insulated my roof, because I can do it better than the "professionals". My mower has been running faultlessly for 15 years, because no "professional" has touched it. Two weeks ago, I spent two hours mowing my lawn, before I realized I left the fuel cap off.
We're all human and SH** happens... not just to women.
