I came home from work the other day to find the front lawn had been mowed. That's odd, the lawnmower is broken, isn't it?
Apparently, Jack took the lawnmower to a small-engine repair shop and had it looked at. They told him it was just the blade, which they replaced.
He brought it home and started to use it, but it was leaking oil! So he took it back to the repair shop. The guy takes it apart, finds the o-ring or washer, puts it back in it's rightful place, puts it back together. Now we have a working lawn mower again!
As Wendy, Bruce, and Robin took turns mowing the lawn this Saturday Jack was yelling "Watch out for the roots!" (which is what broke the lawn mower last time.)
