stuff you're doing while at home

Today I asked my wife for the 10th+ time
"Please be careful when you're pulling the hose through the garden" since she breaks branches & knocks over the irrigation sprayers I spent hours on earlier this spring & she goes into a hissyfit. Why do some people truly believe they are above criticism? Especially my wife ! Lol
If you got an irrigation system set up, why does she need a hose?
