how did this happen?

Last semester I had one and a half groups with beginners (16 people) and we barely had enough people signing up for the intermediates (7 people). This semester, the intermediate group filled up within 48 hours, and I only have 6 beginners. We're considering joining the two beginner groups, which I would like as it would give me time to eat between work and teaching.

I blame the cold weather/crisis/Greece/rabbits
