man with hat

Today a man with hat, hand in hand with his girlfriend, passed me.
2 days ago he passed me at the same place (about the same time), his chin somewhat fore-/upwards, and soaked in air through his pressed lips, making a noise while passing me.
I've seen him twice before, close to my home, not long ago.
Yesterday, on my way to the supermarket, a man dressed with sand-coloured jacket and trousers came towards me, first jogging, then he walked and put his hand at the zipper of his jacket (neck), as a gesture, while he was looking at me.
On my way back close to that point two policemen, dressed in black, came out of a building and passed me.
They wore black leather jackets("polizei" on the back), no hats, and black cargo-trousers (usually from a special unit).

I won't describe all people that differ from average here, i just pick up some that are easy to describe.
That there are people who show a coincident timing ore want to be recognized by me is nothing special, but if the police would be that, it would.
(There has been odd police a few times before, but none where i wondered that they are there at all, just common cops)
