True Stories Donald and Chemistry

I always looked up to my oldest brother, Donald, . because he was both very knowledgeable and because he was 18 years older than me!
One time when he and his family came to our house for a visit, I was studying chemistry from my community college class. When I told him the homework was pretty hard, he said, “You shouldn’t have much trouble with chemistry, I never thought it was very difficult”.
“That’s very easy for you to say”, I told him, “When you took chemistry, there was only earth, air fire and water!”.
