I'm angry at a kid and also her mom for trying to jump into my garden.
My garden is nice, they probably wanted to check it out.
Yes, I have a fucking grass lawn!
Since gardens tend to have plants that are ornamental and fragile, it is understandable that you are upset at a child for wanting to jump into it. People should not trespass onto other people's property like that since it can be so damaging to the plants that grow in that area. You should try to talk with the kid's mom and explain how you put so much time and effort into your garden and would be very disappointed and upset if it ended up being damaged by a trespasser.
It's my garden and they should stay out of it.
You clearly put effort into maintaining it and others should respect that effort and your property. I am sorry that happened to you.
