My 12 year old nephew came up on Thurs and Fri to go around with me on some of my accounts. So, since he asked, I tried to teach him how to use a line trimmer. He's pretty strong and could start it himself (Echo GT200) but since I don't have kids of my own, I wondered if it's too soon or not and here's why. I gave him about a 10 minute explanation and another 10 minutes showing him the actual use of it. He went around my lawn and practiced on areas that I had left from mowing the day before. So, here come's day one and no matter how I tried to tell him, every once in a while, he....well....sucked at it. I would show him how to do it and what it should look like, but almost every lawn I had to go back and show him patches that he left. I even gave him an out the first day but he said he wanted to stay in the truck but things even after the second day never seemed to get much better. I suppose I could go right into a "When I was 12" story but honestly, I think this kid has XBOX rot. PS2 rot. Or maybe even TV rot in his brain. Honestly...it's funny how they can master those crazy games but they can't even tie their own shoes. Come to think of it...he even left me a "Mr Hanky" ion the comode!
