Square Dancing

Square dancing started around last week, or somewhere around there.
I don't mind square dancing, and I don't mind dancing with guys... I mean I have had a lot worse, when I was graduating in China, we had to waltz. Compared to that square dancing is much better.
The problem is there are two times the number of boys than girls. Which means girls have to dance each song twice, and continuously. While the boys switch turns and they only have to dance each song once and they get to sit down every other round.
The first few classes were okay, I didn't mind dancing for the whole time. But after a few classes, it got really tiring. I mean imagine having to dance for the whole time for one whole PE class.
I don't get why boys can't dance with boys. Last year I wasn't here for square dancing, but she said that there were too much girls and so the teacher let girls dance with the girls. I don't see why boys can't dance with boys, it isn't very different right? Instead we girls have to dance everything twice and the whole class, while the boys get to sit down and rest. Not fair!!!
