Why does their have to be a point? People come, people go. Life goes up, life goes down. We sometimes smile, we sometimes frown. Everything is in a state of flux and whatever mood you are in today, is sure to change soon enough. Give yourself permission to feel whatever you want, it's your life. Happiness isn't guaranteed, the best you can do is create and cultivate an environment where happiness can come, a bit like a garden, you create the conditions necessary for good growth and leave the rest to nature, but even when we cultivate such conditions, it doesn't mean that we are immune to outside interference.
