Why does she often record me with her phone at work?

I have been carpooling with a coworker for about 2 and a half months now. We don't carpool every two weeks because of a rotation shift that I do. I have noticed that she records me a lot on her phone when I say hi during those periods that we don't carpool. I can tell she gets excited and starts to even take pics sometimes.

I don't think she likes me more than a friend but, why does she take pics and/or record me a lot? Is that normal behavior?
