Boy you guys need to get a grip.
Including astronomy in every conversation. Wow. That is an obsession. Classic signs.
I rarely mention my hobbies to my friends, they are not really all that interested in Astronomy. Ocassionally I ask them if they want me to bring my scope on a trip away. When I do they really get into the questions and with 12 people it is a long night. However, I would have to say they are more interested in my photographic hobby as this is something they can identify with. Besides during winter I like to socialize with friends and then in the summer they understand.
This also by the way keeps my girlfriend happy and she does not have to worry that I will bore one of her friends to death with Astronomy gobbldeegook.
So; no I am not an astro evangelist and happy that I have my obsessions under control.
Every conversation, did you hear that........
