I am personally not interested in not having fun when I speak in L2 to my kids. It is just so wonderful to be able to choose between activities like 1.talking to the kids about anything (PQA), 2. doing a story, or 3. doing some interesting reading and discussing with the kids. All of those have such high fun quotients!
Whether we do general talking about, say, one word, watching it turn into all kinds of things, or a story, or doing a reading class, more and more, the awareness to connect on a human level with my students is beginning to infuse every aspect of what I do in my classroom.
Because I want to enjoy my life.
