What actually happened, he misread when I wrote my mother no longer lives in the house. Later, when seein him online I phoned him. He was embarresed for and apologised for this "misplaced email. I replied to him not to worry, to err is human. . His email was just him making me clear he was there for me should I need a friend.
In life we meet a lot of people, but only a few remain in your life. Some people just know you and then you have Friends who KNOW you.
It's like with an onion, there are everal layers in Friendship. Outsite these layers are people you meet. In the first layers the people who know something about you. The closer to the center, the better they know you.
Some people reach that inner circle; they got there, not because they wanted to know all about you. They got there as they were there for you in times of need. Times they knew you needed someone and they made sure you had. Times where you didn't need to ask them anything. They KNEW when to be there on the right time. They are the ones you trust.
