Fog

I looked out from our balcony and noticed there was a lot of little fires down below. Maybe someone was having a hangi down below. Then I noticed they were also going to have a big party on the other side of the apartment. This was very strange. Then Glynis comes running out to the balcony. "Close the windows and doors. They are fogging"

Then it all made perfect sense. There was not a big party to which we had not been invited. They were insecticide the neighbourhood to destroy any mosquitoes
