It is surface because he is incapable of connection. It has nothing to do with how you behave or what you do. You only have the power to start a fight or not start one. You do not have the power to to make a connection. It's like replacing only one battery in the remote. It still won't work.
Throw a pebble, a boulder or a scrap of paper into a shallow puddle. It makes no difference what you throw. It cannot sink to the bottom or barely make a ripple.
You are thinking too much about your interactions. He is not in there right now. Just go about your life. And don't ask him to watch your pets. Don't ask him for anything.
You'll know if he is ever someone who could make a connection. You'll know if he is ever a friend who should watch your pets. He isn't right now.
I say this all with love.
I believe I will see the bounty of the Lord in the land of the living. Wait for the Lord with courage. Be stouthearted, and wait for the Lord.
