I use to have some other hobbies where whenever you meet someone else with the same interests, you'll say "hi" and maybe chat for a little. But with photographers, I've met 2 in the streets and none of them responded to my "hi". both of them were just shooting the same events that I was shooting and had really professional looking camera and lenses and had their lowepro backpacks with them. I had a backpack, 50mm lens and 10D so I looked more amateurish, but not that amateurish (I hope). anyway, HOW RUDE!
