As for step-father's dental work, it looks like they'll be able to put it on a credit card and just work on the monthly payments somehow. Maybe I can at least help chip in a bit each month if they need it. They're thinking about refinancing the house to get a better interest rate, but considering how recently they bought their place, I'm not sure it would be enough of a difference to be worth the closing costs.
I guess things are looking up, little by little. Now I should be able to easily afford the groceries for Thanksgiving dinner. Can't wait!
