Wow, Velvet, he actually looks away from you and says nothing? That's... weird. My T was sick a couple of weeks ago and had to cancel a session for the first time in years, and the next time I saw him I asked how he was feeling and if he'd had the flu or something, and he politely told me he did have a flu-like thing and a subsequent sinus infection but he was feeling better, and he thanked me for asking. And then we moved on to other things.
The staring at the wall and not answering thing doesn't strike me as a "normal" therapeutic technique -- to me it comes across as his own discomfort.
