So it's Sunday afternoon.
The condo rules clearly state, and reminder notices were posted recently, that there is to be no construction noise, reno work etc on weekends or holidays.

Yet once again someone is hammering.

Clearly their need to hammer on a Sunday is more important that the peace and quiet of all the human beings in all the units in this building who have to listen to it.

Human beings.
It's a wonder the species has survived this long.
