You ever just hear someone remark about not getting something and light up into the biggest smile because "Holy shit! I know this! It's time!" and you know you could just launch into a massive infodump? Mom's studying for her ESL certification and she remarked about not understanding how Russian was alphabetic and I just lit up. Just, "Ooh! I know my types of script! It's time! deep inhale" That was fun. I don't get to talk about that stuff much.
