Is it possible for a narcissist to be anyone's friend?

I think a narcissit's "friend" is someone who will focus only on them, shower them with attention, and not want to give back. This might look like "friendship" from the outside as some people are just more givers, than takers. However, I think the question is if the non-narcissist b-friend/son is comfortable with the relationship, that there is not much you can do-even though it eats us up inside to see our loved ones being treated badly. It's best not to convince anybody about anything (unless on Yahoo answers!) b/c people will turn it around, and say you broke up the relationship by bad mouthing somebody's partner. while this may seem like a good thing in the present, just have to be mindful what it will do to your son's and your relationship in the long term if you step in. I hope he opens his eyes sooner the later. Blesssings to you and yours.
