Dave

My younger brother, Demyan, had been begging our parents for a long time to sign him up for boxing.
And finally, he turned seven, and our parents agreed.
But on one condition: I had to pay for his boxing lessons. My brother and I were very close, so of course, I agreed.
He had been going for a month already,
And then, suddenly, they changed his coach (it was Dave).
Today was the first session with the new coach.
And I dropped my brother off at boxing.
