I hardly ever make New Year's resolutions, except that I quit smoking every year. (No matter that I've never taken it up in the first place, I still feel a sense of accomplishment every December that I've kept my resolution.)
However, this year I am making two resolutions:
(1) I will knit an adult-sized sweater.
(2) I will not assume that people are Mormon. Ever. Like, even if it's my bishop or the missionaries. (Actually, it would be really fun to ask the missionaries what church they go to.)
As regards #2, I don't think I'm terrible about it, but it bothers me when people do it too much, and I do it more than I'd like to, so I'm going to try and cut back.
