These could actually be the same person, but they are not.
Mr. Mows All the Time -- He mows twice a week whether the grass has grown or not. After he mows, he must notice how the grass suddenly looks browner. This is because shorter grass tends to lose water faster (he must not know this). So, he diligently sets up and moves around his sprinklers almost every evening.
Mr. Waters All the Time -- Every morning the street is wet, along with his driveway and sidewalk. His sprinkler system is clearly the program and forget kind. Or don't give a rat's ass kind. His grass is luciously green, however, even though it's no taller than a grasshopper and looks like a golf course (the only time he is outside is to mow his lawn, fyi--I should know, I'm outside all the time).
I forgot one.
Mr. and Mrs. Water for 5 Minutes -- I kid you not, their sprinkler system zones turn on for 5 minutes at a time (and spray over the fence on me, which is nice since it's hot out). Now what in the world are they trying to water? The air? That grass will have the shallowest root system ever so it can burn often, so they can water more, so I can get on this soap box and box soap to you.
And these are just my immediate neighbors. What do the folks two doors down do? I need a cupcake.
