Practice in Context –
Job Interview Example
It’s unfortunate that
you didn’t try for the job.
I’m convinced you could’ve landed it. It was a great
opportunity.
You should’ve applied! I wonder why you didn’t.
You might’ve
been a little nervous about the interview, but honestly, it wasn’t
worth worrying about—you’re a perfect fit.
I could’ve
convinced you if I had known you were unsure.
In fact, I thought you’d already applied. Just now I learned that you hadn’t.
If I had known you
wouldn’t apply, I would have encouraged you for sure.
With a little push, you must have had a change of
heart—you might have leapt.
