I think you are right about class 3. I did tell the instructor it was largely because I was too lazy to bother doing anything on my own.
and it would be quite nice to roll to class on a Saturday morning and come back for breakfast with everyone. I wouldn't have to watch dreadful family channel Disney nonsense, either. 
The job thing is perfectly legal and above board on that score - my contract was only for a seasonal job, and there's been a month in between the requirement. They are now advertising for a ft, permanent post, so all completely above board. I'm just uncomfortable as I feel a bit in limbo - I had been told that they would look at hours etc once they had worked out their opening times for the winter, and let me know if they had hours I might be interested in. So, I'm not sure if they just assumed I wouldn't be interested in a ft permanent position at this level (to be fair, this would be a reasonable belief based on my cv and the hours I had been doing), or whether they had discussed it and decided they didn't want me anyway. . Or whether they were just expecting me to watch the site and apply...
To be absolutely honest, I would do it for the money as I need it. But the actual job would bore me to tears year round. The library will be really quiet a lot of the time, and this role would require me to sit at the front desk and wait... Yes, there might be a few books to repair, or process, but largely, the role involves sitting at the front desk. It was fine in the summer, as we rotated, and it was busy, and the rest of the time I kept myself busy (I moved every single book in the library to reorg the shelves, lol. And the entire cd collection.). The ft job means that there would be one person running circulation. And sit there. All day every day. So maybe I'm just being a bit prissy and it's all about my ego.
but then I fret that I've decided that because my ego is hurt, and I really want the job.
I'm over thinking this enormously. 
I know I am.
It reminds me of that discussion before about stress being mostly self-induced. 
I really must just get a grip.
Right, on a different topic, I don't ache too much this morning but my foot is being very odd. I didn't realize until last night that it had been bleeding most of the day. (presumably boot camp induced) So now I'm fretting that that means there definitely is still something embedded really deep. The night before, it had seemed to be healing really nicely. Bah.
I have ten thousand things to do today, and I have been mining for two hours.
Feck.
