shoes and jobs

Remember how January was the world's slowest month? Well April has been just a slippery slope, I haven't been able to keep on top of it.

The Museum wants me to work the month of May as the Stewart Fellow again. I told them part time. And even that makes me exhausted. I will also be teaching twice a week, and just preparing lessons, grading and office hours will put me at at least 12 hours a week, if not more. This has been a hard decision...part of me thinks I shouldn't do it for health reasons, that extending myself that much with twins can't be good for my body. What if it made me go into premature labor? Nothing's worth that.
And the other part of me thinks that this will be the last time in who knows how long I'll be able to actually bring money into our little family unit, and it's only four weeks, right?

I just don't know what to do about it.

My formal black shoes that I wear on days I have to give tests or review sessions to try to differentiate myself from the undergraduates, who really I'm only a few years older than, no longer fit on my swollen feet. So I had to wear my daisy converse, which are my favorite shoes, but they don't exactly exude "authority." How can I tell a student the difference between a triforium and a gallery in a tripartite nave elevation, or point out that Wikipedia is NOT a scholarly source, when we're wearing similar shoes?
