Friends are luxuries, and luxuries are all impractical things (gold, beauty). You should be satisfied with this kind of thing, because a true friend can give you nothing but friendship.

China people's work utilization-the traditional idea that friends are useless-has no work utilization. Making friends is not for use, shelter or a safe exit. Friends are so important that they will not be allowed to take utilitarian purposes without any sensory stimulation. There can be no non-friendship factors in friendship. A friendship between gentlemen is as light as water, but it is not often remembered but everywhere. Friends are not practical goods, but luxury goods. Once you have them, you will feel satisfied.
