Since when is Half Term a holiday?

Cor, don't half-term keep you at it? And I thought it was supposed to be a break. Every day has to be approached with military precision. There's revising for exams in the next half of term, there's music practice "it's so good to do it when they're not tired", and naturally enough loads of work to be done for school. Oh yes, and we have to squeeze in Nanny McPhee and Oliver. And every night has to be a late night "but it's HALF TERM, Daaaaaad. Duh!" I don't know how I squeeze any work in. I think I need a holiday.... .
