You shouldn't change a friendship based on sexuality.
Paul recently became aware that his friend, Scott, is homosexual and Scott has invited him to go out to the bar with him this weekend.
Paul has to respond to Scott's invitation.
Paul considers the fact that his sexuality is different from his friend's, but he realizes that it doesn't matter and goes out with Scott, as he usually does.
Paul enjoys spending time with Scott, but he decides that he doesn't want to continue hanging out with him because it makes him feel awkward.
They have a great time over the weekend and their difference in sexual preference never becomes an issue between them.
Scott is hurt that his friend is clearly no longer accepting of him and Paul misses the time he used to spend hanging out with his friend.
