Hard to have a nice yard, when neighbors have a Dandelion Nursery!

Why judge your neighbor and complain about what they do on their property? Is he trying to compete with the next big thing or enjoying his own life.
Likely does not have a green thumb and can't frown on him for that. Possibly finances are weighing him down?

It's too bad the world has got too judgemental of others.

Go offer to help or go do it yourself stop pressuring others for their choices.

why i will tell you why, ever try to sell your house when the house next door or across the street looks like the city dump, it's called respect for your neighbors, when you live in a community there's a level of decency that is expected and it is your right to disagree and live out away from others, it's a sad world that people have to be told this
