the last request

An excerpt from a letter:

Dear N.D.,

Is it worth it for me to waste so much of time and effort on you? Sometimes loving a person cannot be measured by what is worthy and what is not. But when it hurts I tend to find solace from such mundane questions - hoping that I can talk myself out of grief which probably ends in my finding faults with you. The fact that I am unbelievably attached to you is my own doing but can I blame you for being insensitive and temperamental? Talking to you is like corresponding with a wall. Even when I hit a wall I hear a "bang". With you I get nothing in return. Not a sound.

Maybe you are merely protecting yourself from receiving what others want to give you; something which you didn't ask for. Maybe I am really stupid for giving what you didn't request.

Perhaps silence is the best reply you can offer and retreat is the best move I should take.

From your childhood friend,
M.S.

Note: How about using that as the opening of a novel?
