I suppose that's one way of putting it. Well, I guess it's fine as long as he knows what he's thinking. I ran into him the other evening and he was being his usual self, then suddenly it was as if a switch had been flipped... after a few minutes of that, he was behaving normally again.

Then again, it's not unusual for people to wear masks to conceal their true selves.

[Tear herself knew about those masks well enough.]

He did... if you want to call it a greeting.
In any case, he's helpful as long as he's not asking a million questions.
