First off : convince him that these people writing the emails or texts DONOT know him ! As JESUS said .... the Fox will not try to enter the hen house dressed as a Fox 🦊 ! The conmen or scam artist first try at getting people to open the messages they send , is to make you relax and feel that they have your best interest in their hearts ! NOT SO ! Unfortunately no security stops the scammers , the best way is to just delete them as soon as you see them ! There isn’t a day that goes by , where I haven’t won 3or4 prizes for something that I did Not enter ! ONE FINAL note ..... there is no free lunch in this world !
