That’s how fear can sound when you feel misunderstood.
Your coach is the closest thing you have to a parent during your four years in college, and ever since you were an infant your parent was there to understand your needs and feelings without you having to communicate them.
As an adult, of course, nobody can understand your needs and feelings if you don’t communicate them. But still, we all harbor an infantile desire to trust someone so much that they can understand us the way our parents did when we were children.
When we don’t get that understanding we sulk. We say inside, “F*** you, Coach.”
There is no preventing the sulk, and it has no remedy.
The best solution might be to simply recognize that it’s there and move on. Maybe the next day you can even laugh at it.
