I know who they are, of course. And birthday and their sons and daughters birthdays. That's how we give gifts. We know who they are and where they are as well - we wouldn't hire them without knowing that.
They couldn't relate - my bad day would be related to losing a few points on a foreign exam or if my favorite restaurant was overbooked.
No interest in learning who they are? What they like? When they have birthday?
If you have a bad day, for whatever reason, you think they couldn't relate to having a bad day?
