First, there is no law that requires you answer your door for anybody (Diablo 3 Gold), even police.
Agreed. These days, I answer the door. If I dont recognize them, they get one sentence to establish their purpose before the door quietly closes. I mean it. I dont bother with the kind of bullshit that knocks on the front door these days.
Also, a stranger who shows up unexpected should have no expectation of a warm welcome
Yes, yet most people ARE polite. The whackos and con-artists can therefore utilize cold calling as an effective door opener (so to speak) on average. My GF - a super polite hoity-toity sweetheart who would NEVER offend - will pick up the phone and listen in silence for 90 seconds before she says "No thank you" and hangs up. Give the calls 5 seconds, 10 at the most. Then go on-hook. Politeness makes us unnecessarily vulnerable.
I have a fence all around my house and locked gates (Diablo 3 Gold)...and no way to be alerted of a visitor apart from their car horn. This arrangement is fine with me.
Wow. You sound like a "people-person" too.
So, be as rude as you feel is right to those that bother you needlessly
To which I add, you dont have to answer every phone call, you dont have wait for a lull in the conversation before you break it off, you dont have answer every question that is put to you.
And most importantly, in high-pressure sales/social situations, remember you dont need a reason to not do something (Diablo 3 Gold):
"What is your reason for not joining JW?"
"What is your reason for not buying gold from us?"
"What is your reason for not identifying yourself to me?"
"What is your reason for not contributing to Barrack Obama?"
Answer: "I dont need a reason."
