When boys are selling things at the store to raise money for a team or for the boy scouts, they tend to stand around joking, punching each other in the shoulders and looking as though the last thing on their mind is pushing their product. When girls are selling things for their team or the girl scouts, they seem much more focused on the task at hand and rarely let anyone go by without at least asking if they are interested in buying something.
No moral here. Just something I’ve observed.
