What do you make of this???

So last year we redecorated the dining area and had put our old table and chairs outside while moving the new ones in. A nice neighbor dropped by and asked if we were getting rid of them, and we said "yes, if you'd like anything there, help yourself." He took the set.

Yesterday I heard an infernal banging and peered out the window to see said neighbor beating one of the chairs with a baseball bat. Just really pounding the poor chair. There didn't seem to be any purpose to it, as the blows were all over the thing...not to mention nobody on our street has a fireplace so it couldn't have been for kindling. I watched, and he just beat that chair senseless. Then he left it there. All I could think of doing was checking the deadbolt on my front door, because I didn't think dialing 911 to report chair-beating would make me look very sane.

Should I now be frightened of this neighbor, or do you think there could be a rational explanation...

Is he...out of his tree or something?
