Return From Whence You Came

I live 19 floors above the ground.  I have my windows wide open, enjoying the fresh air.
At least I was.

For the last hour, my living room has stank of Indian food.  Specifically poppadoms.  We have no Indian food in the house.  You can't smell it on the balcony, so it's not coming from outside.  You can't smell it in the hallway, so it's not coming from the neighbours.

Weird.  And not a good weird...
