Yes....and no....like RB said...that's basically a judgement call on the person. I personally if i see a dog...or a sign of any sort i just skip it and go to the next one....I've had people yell crap at me...cuss at me...call the cops on me...it's not that serious...if someone came and knocked on my door at 10am if i was too tired to answer the door i wouldnt....if i did and i saw it was someone i didnt want to speak to then id just say im not interested and go about my business...as i stated...a firm no thank you and im off your doorstep...You might not be interested in what i have to say...but maybe your neighbor or your neighbors neighbor...that's why we do what we do. But like i stated...a simple sign as stated before will keep us away from your door....you could even tell someone not to come back again and each local congregation has a list of houses not to go to. Sometimes people think that we're gonna jump through ur window and start chucking watchtowers and awakes and bibles at you like ninja stars if you say no thank you.
