At times I've had more female students than male students - don't know why. I think the differences between individual students is much greater than any male / female differences. I just think of them all as students.
Anyway, since this thread is about funny comments I've had quite a few. One that sticks in my mind was the first sentence spoken by a (foreign) student (about 15 hours in his log book) on being introduced to me for the first time. He said "I need to do my first solo today". One glance out of the door at the windsock made this quite funny.
