Alice used the word "alas" when talking to me. I don't remember the context but it isn't important. I mentioned this amusing vocabulary choice to Molitor in front of Alice. Mere minutes later, Alice said, "I miss my friends. I wish I could have a play date with Mallory." We've been expecting her to be sad about abandoning her friends, so I was gearing up to comfort her when she looked at me and sighed, "Alas..." with a huge grin on her face. She had staged the conversation just to use the word again. Awesome!
