Give or take?

A couple of days ago, a conversation.
I stretched my hand to give friendship and found I had put my fingers into my friend’s wounds.
I saw that my seeking to make friends here might seem from another angle like a kind of greed.
Is it right to take a person’s friendship, to seek to become important to them, when they have an established life and you are a stranger and will leave, when you know the open doorway in their heart and that it is a difficult thing not to give?
We are closer now. I am good at sharing people’s sorrows; less so their joys, it seems sometimes. I hope it will not be so.
