No need to ask permission of those men because they were actually working on the grounds of our condominium complex. I am one of the many owners of these buildings and common grounds areas. That was (partly) my tree they were cutting down!
Aside from that, it was fairly early in the day [for me] and I had not yet showered and dressed. I certainly would not go running out there in my nightclothes! I was able to shoot the photos from the comfort of my own home, right out the window.
As it happens there is construction going on at the public school building in my neighborhood, too, and tempting as it would be to shoot photos of that and men at work doing interesting things with fascinating machinery, I am not doing so because that would be inappropriate: it is not my property (although of course my county taxes do help pay for the public schools and construction projects on schools, libraries and other county properties).
