Context: I plan on doing some more work next weekend , by which time I 'll have regained my strength . It really is the most satisfying work ; I used to do chores like this all the time growing up , when I had a huge backyard and vegetable garden . Some of the neighbors would let me trim their trees when I asked , and I 'd climb around in them with a hatchet and a hand saw , cutting off the branches that were growing too close to windows and power lines . I 'd rake leaves and pull weeds for dollars .

- They like to stay inside and watch the trees
 - None of the above choices .
 - The like to climb up on the power lines .
