"I noticed today that they were stolen. I think they were taken by the guy two spaces over. There was a stack of bricks behind a tire on his utility trailer, but I'm not 100% sure whether or not they were there before."
This says to me, the OP saw his bricks were missing, and he walked around until he saw some bricks and assumed they were his.
He doesn't even know if the other guy had bricks before his went missing.
Suddenly the poor guy 2 spaces down is labeled a Brick Thief, and posters on this site are out for blood..:)
My first thought was that like the storage facility I once used, the first time the maintenance man came by with a mower he would have moved them somewhere else so he could cut the grass.
PS: I only posted because I want to see this brick travesty reach 7 pages
