I must have looked like a complete retard in topology even through I was correct.
I wasn't paying any attention to the lecture because I was too busy thinking how to do the last question in topology coursework. Anyway, for some reason he stop and was asked if anyone knew why they called it a lemma. For some stupid reason, I automatically said flower.
I didn't know why at first I actually said flower personally I didn't mean to say it, but then it came back that in a book I read three years ago it saying the motivation behind various Mathematical terms.
