I thought we were just friendly bantering....
However, to seriously address the OPs, ummmm, "instruction":
I open carry 90% of the time, if not more, and 90% of the general population never notices or shows no indication that they notice. When I choose to conceal my gun, I move my shirt from behind my gun to over it and nobody has ever said anything about my gun, except for my wife or daughter who might comment, "No gun today?" Reply, "Yes, I have it right here." I carry a stainless steel Taurus PT-145 in a Fobus OWB Paddle holster.
So, EXTREMELY IMPORTANT to dress around the gun?!? Really? Not in real life. I find it sadly humorous the great lengths that some people will go to bury their gun so deep under clothing while sacrificing the ability to rapidly deploy the gun - without a whole lot of noticeable movement - to convince themselves that nobody has any possibility of noticing their gun.
Just because no one says anything doesn't mean that they don't notice it.
The whole purpose of concealment is to APPEAR as if there's NOTHING on your person... Not to have a bulge showing under your shirt. DRESS AROUND YOUR FIREARM!
It's different from where I'm from. If you're not a Police Officer, Security Guard, ATF, CIA, FBI or Border Patrol Agent who USUALLY carries it in plain sight, then it usually brings negative attention to you from either "OH MY GOD! HE's GOT A GUN!" to the police stopping and harassing you or someone might be plotting on you to try to take it off your waist!(in very few cases will the last situation happen) It's BEST to keep it concealed to keep the negative attention from off of you as well as not giving people the "UP's" on you.
