If you know your friends, you won't care if you treat them well.

If you don't know your people, you may have more ideas. You may think that you usually skimp, or to put it mildly, you are frugal.

Sometimes, you can tell the right people what you say, but you never treat them unless there is a special reason. Otherwise, it will take a long time to make friends. Although friends don't say anything, they must have ideas.
