Just a thought.

If you want to go to people's doors and tell them about Jesus, don't send the socially inept who will stand at a glass door and just stare inside freakishly while a small dog yaps wildly, waking a newborn up from his nap, who then starts screaming, and the mom is on hold on the phone trying to get a referral for her daughter while folding laundry at the same time and then when she answers the door amidst the chaos of screaming baby, screaming dog, and screaming elevator music on the phone you just kind of stare at her until she sighs and says "WHAT?!" and say "We'd like to tell you about Jesus."
