If there are bricks surrounding a tree, with a bunch of tiny plantlings growing, you shouldn't weed-eat inside said bricks.
Is it really that hard? And when you see someone visibly upset about having their plants destroyed, the appropriate response is not "I guess you can learn how to weed-eat then."
I don't burn dinner, and then say "I guess you can learn how to cook." ugh.
Vent over.
