1.If you don’t answer when I knock, I’ll try the door. Occasionally, I hit the jackpot and walk right in.

2. If I am ambitious enough to invade your home while you are there – you may want to consider “answering” my door knock through the door – “Hello – who are you – no, I don’t want any – go away or I’ll call the police” And I will go away. So DO NOT OPEN IT! But if I hear your voice speaking with me – I will move on to another home that may let me in!

3. Maybe I will work with someone claiming to sell magazine subscriptions – I always know when someone is home or not – by knocking on the door!

4. I look to see if your trash cans are put out on trash day – or I’ll look to see if anyone has taken in the trash cans by nightfall – a dead giveaway that no one is home!

5. Those car keys you left in the ignition or on the hook in the garage – allows me to drive away from your house in luxury with your property – and your car.
