Grab,

Dandelions and moss are plants - and so is 'grass'. Have you ever given any thought to why you favour one sort of plant over the other? And having chosen 'grass' (obviously! ...?) why you devote so much time and effort to keeping it just a few mm high?

Have you ever thought about what functions dandelions and moss serve - or were they put on Earth just to annoy you?

A friend of mine has Romanian daughter-in-law. She asked the Romanian woman, "what was the first thing that you noticed about England?". And she replied, "all the short grass - why do you need to keep the grass so short?" So your choice of plant for your back garden may not be as 'obvious' as you think.
