Amos and Maggie are way into puzzles these days. Amos channels Snoop Dogg and calls them "pizzles" (thankfully, he has yet to say "fo' shizzle"). Maggie is slightly better at the puzzles, and sometimes when I am too busy to help Amos, he'll ask Maggie to help him.
It's extra adorable to watch them work on something together. Sometimes I'm "busy" on purpose.
