Think back on who you've interacted with in the last couple of months. Don't focus on if the issue would be big enough to warrant such a thing, after all... if it was a big thing to you, then you'd have thought of it by now. It may seem more of an issue to them than to you."

He settles himself comfortably, thinking, eyes a little distant.

"Could it be a... client?" he ventures, delicately as he can.
