How the favorite Texas grandma was persuaded

For the purpose of not having to write "the favorite Texas grandma" over and over we shall refer to her as Grandma for this blog.

The youngest child and Grandma had just finished cleaning a cabin in record time when Grandma commented,
"What on earth are we going to do for the rest of the day?"
The youngest child, who does not often think, replied much to her own horror, "There’s some trees I was thinkin of cutting down this afternoon." The youngest child would much rather have kept that a secret.
Grandma raised her eyebrows and stared down the youngest child with a look that everyone else would have known meant, "tell all, or else".
The youngest child returned the look with her own annoying habit of always appearing to not get it.
"Cut it down with what?" Grandma asked with an authoritatively demand and high voice.
The youngest child’s blank stare hid all feelings of panic as she mumbled in all logic, "The chainsaw."
"Not while I’m here you wont!" Grandma heroically held her ground. Just then the middle child called all the attention to a different problem and the discussion was over much to the youngest child’s relief.

Two hours later, Grandma brought the subject up again while taking her two naughty grandchildren on a walk.
"You weren’t really going to use the chainsaw were you girls?" Grandma did well to not sound patronizing while deliberately including the middle child in a discussion she had not been apart of. She had high hopes of appealing to a level head.
"Sure, we need to practice, in case one goes down on the road." The youngest child explained in her twisted logic.
"Yeah, then we won’t be as shaky when the pressure is on." The middle child sided with the youngest child much to Grandma’s dismay.
"Well, just don’t do it while I’m here." Grandma stated again to put an end to it.
"But we’d much rather do it while you’re here to help if something goes wrong, rather than when its just the two of us, Grandma." The youngest child said uncomfortingly to Grandma. It was, however, enough to silence her on the subject.
