Is it normal to have this feeling during my break?

Last week I began my 3 week winter break from school(so now I only have 2 or less weeks), and I absolutely love being away from all the school work.

However, over the past couple of days I've been left with a feeling... a feeling that I actually miss school and want the break to end. That I want to be at school doing work, instead of staying at home doing nothing. Keep in mind, I have nothing planned for this break except stay at home, and occasionally go out if the weather is nice.

I love having the time off, but at the same time I'd like to be doing something so I don't get bored during the day. Is this normal?
