It makes no sense to fix what you can't change. People are annoying, they disappoint, they make you laugh and then kick dirt into your eyes. The point is to find one good thing about someone and roll with it. Smile for as long as you can whether it be for an hour or a minute and laugh fully over something that doesn't make a bit of sense. The whole optimism bit Is slightly overbearing theres no reason to force the glass in front you you to be half full when all you can see is empty but it's enough to be pleasant. It's enough to smile for a second longer.
