In first grade music class. I wanted the tall xylophone and was unhappy that being a larger kid, I was stuck with a small one. While lamenting that fact, my grandmother told me ask for what I wanted, So I the teacher before the next class.
So I approached the salt and pepper haired woman and asked her. She remembered and I got a not small, but not the largest xylophone.
At that moment in the disappointment of having asked and not gotten what I wanted, I the learned the second lesson, be specific.
The request should have been for the largest not larger instrument.
The third lesson, was to speak up quickly since I said nothing not wanting to be difficult and the issue went partially unresolved.
