Now I'm gonna ask the other question, why didn't you notice the mortar falling down? :))))))

There was a snow and I probably neglected amount on the neighbour's space, there was much more falling on the roof below, and I was ok with that since that space is trashed anyway. Also I knew there was nobody living there, so I was just like meh, it will fall down eventually with rain ets. Yeah, I think I'm just sloppy worker.

@drlobes on the service of deepened self-inquiry :D

Well, you had plenty of reasons to be sloppy :))
