My sister and I had a lengthy argument about whether or not she was allowed to name her kitten "Loki". Neither she nor my parents understood my flat "No. No. NO. NO. No. I will keep saying no for eternity. NO. No pet under a roof I live in will be named 'Loki'. NO." But eventually they realized I was serious, and gave up.

(So he's Optimus Prime instead, Appa for short, because he is white and shaggy and fluffy.)
