Girls get lost and waste lots of time on “lists”.
No, being on a list does not keep a girl waiting. She can see who she wants, regardless of how many boys have her on a list, as long as she hasn’t yet agreed to see someone else. In fact, since the boy usually has to wait for an answer from the girl, not the other way around, the boys waste more time than the girls.
True statistic: with the rare exception of double-dipping, the exact same number of boys are busy, at a given time, as girls. Why then are boys busier than girls?
The reason the boys are busier is because there are fewer of them.
