I was driving to pick up my wife today, and the main road I needed was closed for construction. So I took the detour, and then came to a road completely closed off for an emergency. I then took my own detour.
As a new teacher, naturally all that I think about is teaching right now, and I thought this relevant. In the classroom, there will be detours. Sometimes they'll be predictable, sometimes they'll be surprises. The route may change, we may get lost, and maybe we'll see some things we didn't expect to. However, as long as I know where we are going, we'll get there.
I like that.
