I'm a total Astro bore myself.
I can work astronomy into ANY conversation AT ALL.
Imagine, about to be anaesthetized for a seriously major life changing operation, and what do I talk about to the anaesthetist? Not "am I going to survive 5 hours of surgery", not me buddy, I rabbit on about seeing the constellation Orion rising above Moreton Bay that morning on my way to the hospital.
I love this hobby/lifestyle.
