So I've realized I have an inordinately difficult time distinguishing between 2 types of "huh"- the hm-that's-an-interesting-thing-you-just-said huh and the I-don't-understand-what-you-just-said huh. Sometimes if I stare at it long enough I can figure it out, but I'm never completely sure. There's probably some fascinating psychology behind this, so, get on this.
