You Friend Named, Unperturbed

See life (people) will not always go as you which. In fact it might not in most cases.
You can either be upset, unhappy, perturbed, sad, or any qualifying emotion that fits the situation.
That's just life. There is ABSOLUTELY nothing you can do about that.
Except one thing.
Your response.
To the situation or situation or to the people who made you feel the way you felt.
You could react positively. Or negatively. Or be Neutral.
The rightness of each is contextual so none is better than the other.
But knowing that the very thing you are bothered by is almost certainly not going to matter in a year time, let alone in a lifetime.
