At the moment she was playing the role of friend.

Just say you're the child of an old friend coming to Earth to continue your studies.

Then after a long time I got up with the help of a friend.

Which doesn't sound like much of a friend to me.

He had certainly played the part of a friend in need.

I got a call from the wife of a friend who died today.

I haven't been much of a friend to you or anyone for a very long time.

He died the next morning at the home of a friend.

Perhaps he was making too much of two friends simply trying to get to know one another again.

I mean, some of my best friends are white people.
