history: I was teaching a cake decorating class that I've taught many times before.  I knew I could teach my students with ease. Next month I teach a beginning cake decorating class. Do you have a lot of experience baking cakes? Yes_comma_ about 5 years.  I've also taught this class before.
current: Sounds like fun. Are you excited?
next: Kinda.  I'm excited to see who takes the class and help them learn to decorate cakes, but teaching the class is the easy part.
