How should I deal with this distraction during therapy?

I just came back from a therapy session. The first counselor that I dealt with had these expressive eyes. They would get huge (extremely wide). It was distracting.

You may know the type. You meet up with an individual, who at first, appears normal. Then, while talking with them, you notice that theirs eyes get bigger (expressive). I’m talking huge (think Princess Diana eyes, but, really, really huge and expressive). It can be a distraction. I don’t know if it’s tick, or nervous habit. How do you deal with it?

Serious question
