Extreme nose blowing and a new invention - the "third sock"

This is a compilation of odd observations: 

* Up til this morning, I have never seen a person blow their nose on a leaf.

* In the park, I saw a couple - on two bikes - holding hands as they biked along. Dangerous, but nice.

* And strangest of all. I saw a police car flagging down a car which had gone late through red lights. Fancy that - the police actually stopping a car for a minor traffic infringement.

~ I also have a tricky question. A certain rather delicate part of me got pretty much frozen on my way in this morning. I'm wondering if anyone has yet invented a ... "third sock"?~

Never never clear your nose ...
