Your neighbor crossed a line. I'd stack my wood a little higher so he could see it looking at him over the fence. Then I'd plant some ugly weed on top that just looks like pure hell. Obviously he's a jackass so no need trying to kiss his butt to appease him. Worst you will get is a judge asking you if you would be willing to move the wood, if it ever came to that. HIGHLY unlikely.
