Camera shy?

Apart from the looming exams, what serves as a deterrent for me from leaving the comforts of my room and take photos with my trusty Canon is the fact that people might smash the lens of the camera into the lens of my glasses... What am I talking about? Well if curious read here.
I guess we live in times where we must be more conscious and suspicious. It's a jungle out there... And I guess I can relate as to why people are so hostile.
Sigh... I just want to get a few nice shots, that's all...
