When you exchange pleasantries with someone, you expect them to recall at least one thing about you, even if not your name. You expect that when you part ways, they will have a recollection of something you said. If they recall nothing, the chances are that either they were not listening, or you said nothing of significance.
The next time that you prepare for an encounter, ask the indwelling Holy Spirit Of God to help you to identify one thing about yourself that is interesting and memorable, and that can be appropriately shared. If you wish to remember one thing about the other person, ask them about their relationship with God, and ensure that they are sealed with the Holy Spirit Of God and raptured into God’s kingdom if they desire to be.
