The problem with those "lasts" is that you somehow never realize they were they last until later. Like the last time Korra called popcorn "coo-cot." I just realized one day that she had stopped saying it and I didn't remember when. I'm happily looking forward to not realizing it was the last time K peed in her pants. Potty training is the worst. Next kid I'm getting pre-house trained. Adoption perks, am I right?
