Anyway, as far as I remember, you (4) …………………………… it here, because you were

And now my news. Guess what? I (5) …………………………… to your part of the world next month for a conference! My professor wanted to attend it, but now he’s heard that some important scientists (6) …………………………… our laboratory at that time. So, you and I (7) …………………………… each other sooner than we expected. I’ll email as soon as I know for certain.
All the best,
Robin
