Day two. MAN my head hurts

I met my student today! :) She is an absolute sweetheart! She came right up to me and put her face in mine and yelled. More like growled. Then she grabbed my hand and we were friends. She is completely non-verbal so far, but I think she's smart. I can see her actually processing things. It's really fun to discover the world through her eyes. Her senses are all really heightened so she hates noise, light, smells, strong tastes, and pulls away if I touch her hand unexpectedly. She loves music and I can hear her humming sometimes. She hates to eat anything but candy, but she actually ate half a chicken patty today. Many teachers were impressed. We had a really good day, and I am excited for tomorrow.
Now for the news:
Before Rosa got there, the principal pulled me aside to ask me a question. She wanted to know if I would be interested in an afteroon sub job, from 1:30 to 6pm. I would basically be helping kids with homework, playing games with them, and helping out with administrative duties from time to time (like imputting attendance). Since my Aide job only goes to 12:30, that works perfectly. God is good! :) I knew He wanted me to take this Laton job, but I knew by al worldly standards it was the inferior job. God knew.
Now my predicament:
I still work for an elderly lady, running errands and fixing miscellaneous things around her house 6 hours a week (M, W, F). I have already moved that to after 1:30, and with this afternoon job out in Laton, I would not be able to get back into town until after 7:30. I could go straight there and shop for her, but that would mean I get home around 10. Not gonna go over well, being married and all.
So I talked to MV today to let her know my predicament, and we decided that I would start coming only twice a week (probably t, th), and I would stay for only an hour. She would have to have her grocery list ready in advance so we don't waste time getting it put together. She wil also save a great deal of money this way.
My ony concern is that that still gives me two 11 hour days a week. DO I want to do that? Maybe for now. Maybe this is just a season of saving. I will not always work, so maybe it's ok for now.
We'll see.
Time for a nap. I'm exhausted.
