I'm (not) watching you

"I know, it does look as if I'm trying to keep an eye on you." says the Boston Gentleman.

"But, really, I was just coming in this room anyway."

"I just happened to be here when you turned around."

"And I am certainly not watching you, " says the Sidekick Cat.

"I am not even looking at you.  Not me."

"When I DO look at you, you'll know it."
