I go out of my way, every day to make sure im not the star of my own show. Used to play a game with others in training classes to spot them before they spot you out in public. I kinda always glance folks over who can kick my ass, or people who seem otherwise sketchy. Make note of exits, cops in the room etc. But Im probably the exception. I mean, what do I have to be paranoid about?You’re being paranoid, which is normal. Most people are stuck in their own world (They’re the star of the show that is their life) and don’t have the slightest inkling what is going on around them. MAYBE an extra observant person can tell, but that depends on where you’re concealing it. Is it in the waist? Outside the waist? Kidney? 2 o’clock?
As @the_owl said, might be too big for the spot where you’re trying to conceal it. Use baggier clothing. Wear a light jacket unzipped.
