Neighbor problems.

[Atoli]

Look:
Neighbor demanding dude not use a chimney because it's in his view? Jerk.
Dude upgrading to larger chimney to spite obnoxious neighbor? Hilarious. And justified.

If more than 2 lines of text are too much of an effort to read for you, I'll make it simple:
Neighbour asking if it would be too much to not to use a chimney because it's in his view? Just a simple request you can turn down if you actually care about your chimney.
Dude upgrading to a larger chimney just to spite someone else who didn't hurt him in any way? A jerk.
