I just came up with a few myself,
What about when:
* You drive down the M4 and wonder where the Antares turn off is?
* Your favourite beer glass is FPL51 ED with a 2x barlow built into the bottom
* On a clear night, you gaze up, see a satellite and refer to it by name.
* You get PMT every two months just before the AS&T is due in the letterbox (Pre Magazine Tension)
* On clear nights the neighbours see you outside with two sets of binoculars, a laser pointer and a massive telescope and
no longer call the police or bother to close their blinds when getting undressed.
* You wonder why the kids school photos dont have "diffraction spikes" in them.
* You scour the Crazy John's and Telstra Shops looking for a mobile phone with a 6MP modded long exposure camera with T-thread and IR filter removed with peltier cooling and has a Vixen style dovetail bar as an option.
I am sure I will come up with more.....
Cheers
Chris
