I just wanted to drop a quick comment. Yesterday I missed a package delivery that needed signature. I was home he knocked once and returned to truck by time I got to door and as I opened door he pulled away. I'm not old or slow to get around but, he didn't even give me a chance to get to door. Didn't look at house before he pulled away one last time. If he had he would have seen me standing outside. My advice is wait a few seconds at door, use doorbell, don't knock ïf there's a doorbell. Some people are hard of hearing and don't hear knocking. Take one last look at house before racing away. Thank you.
