Relief...

It has happened to all of us: things are going great in a class when suddenly an unexpected event jeopardizes the success of our lesson... What should we do?

The answer, of course, is to adapt to what has happened... We have to use our intuition, resort to our previous experiences and "pull a bunny out of a hat"...

But that's ok, is it not? That is an important part of what teaching is all about! So let's enjoy it!
