I make it a habit to always be conscious of anyone near me or by themselves. I will motion for them to come to my herd or I will go and get them and bring them to the herd. I find that this ability is a lost art. I would love to teach others how to gather, but first they have to have eyes to see.
Once I have made someone feel a part of the herd they feel as if they trust me. I respect them and then they find it very easy to get to know me.
I take the philosophy of doing business with people we know, trust and respect and work it backwards. And it has to start somewhere. I choose to respect others by making them feel wanted and included. The rest is easy.
