I have a question, please forgive me if it has been answered elsewhere.

You join an Internet programme on the basis of a friend's referral. By doing so, you are both entered into a contest to win airline miles.

You win a whole mess of miles. Your friend wins nothing.

Your friend refers to your prize as "our" miles and tries continually to butter you up to give/sell at deep discount your miles to his friends and relations, on trips that you are not invited on.

Never mind that you had plans to spend your miles doing something else for yourself, your family, your special someone. You have already spent a few on trips for yourself.

Whose miles are they?! I believe they are MINE and as an only child, I don't share well. Other opinions appreciated.
