Today he started at 6:25 and stopped at 6:35 but did not hear anybody climbing down the stairs. It happened before, i heard his older Toyota (big) SUV starting seconds after the last noise upstairs. But today the SUV was not here, and the noise simply stopped.
There is a coincidence with stock market which starts at 6:30 local time, always goes down around 1% and then recovers starting at that point. What does this mean? Still have no clue. Today i was waiting impatiently for him to leave because i was feeling the smell inside and wanted to get rid of the source.

There is a new pattern with the poops as well. Flattened. He/she steps on them right after.
And the unbearable smell of those in bags unknotted in the dumpster.
7:25 One guy, tall, thin, with a moustache, looking Latino, dressed in a green neon jacket came with a lab of about 6 months, let the dog poop in my line of sight as i sit on the couch facing the computer and wall sized window and left without picking.
7:45 I have become nauseated. Everything i ate earlier for breakfast has become something else in my stomach because of bacterial contamination from breathing.
