What do you do about mowing the front lawn/nature strip at your place?
My father has mowed my brothers' lawn twice (once when they were gardening together, and once when I was house sitting). He mowed the whole strip ie all the neighbours lawns (townhouses that all look pretty much the same and aren't too wide). We were there the other day and noticed that some neighbours had mowed, but only their own space. When my dad mows the nature strip at home he will always do the neighbours too.
So, my question is, what about you guys (that have front lawns/nature strips). Would you as a matter of course mow the neighbours front when you did your own? Would it depend on the situation?
