That won't happen. ✬

Let's consider the worst that could happen. ✬

I didn't want this to happen. ✬

If you know that something unpleasant will happen, that you will go to the dentist for example, or to France, then that is not good. ✬

I don't care what you say. It's not going to happen! ✬

Something terrible is about to happen. ✬

I have a feeling that something dreadful is going to happen. ✬

I'll keep my word, whatever may happen. ✬

What would happen? ✬

Nobody can foresee what'll happen. ✬
