lol this reminds me of that time on chemistry class, one of the guys who didn’t want to be there asked the teacher “what am I going to do with chemistry in my life? Like if I become a car sales man, what use is chemistry!?” and the teacher just quietly muttered the answer… “well I wouldn’t buy a car from a guy who doesn’t know the difference between hydrogen and petrol…” and then continued the lesson.

The guy was pretty quiet for the rest of the day lol.
