Need help understanding people

Well, last night I had one of those occurrences that make me wish I understood how people interact with each other, and I'm hoping you guys will help me.

To make this fun, lets make it a quiz:

A female employee returns to work after an injury, and a male co-worker comes up on her first day back and says with a stammer that he had been praying for her recovery.

Now, is the male co-worker: A: Just being nice

B: Being nice, but also kinda flirting

or C: mostly flirting

You add in the difficulty of the fact that the female co-worker is in fact trans, and you can understand why there is some confusion.

So folks, let's see who takes a crack at this, and the person with the most creative answer (as judged by me) will get a "no-prize"

I look forward to seeing the responses ...
