The third time you run the other way screaming.
Most assuredly not, Dogbert.
Third time you’d head butt him and take out a restraining order . . .
The third time, you say something pleasant, like, “The more I see you, the uglier you get!” Of course, then you need to run like a thief!
Oh, carp! (That’s a metathesis, isn’t it?)I think third time you halt abruptly in front of him and say “why are you stalking me?”
Miss Manners would have had you throw his chair through his window. And then hand-write an apology letter later.
I would have probably just smiled and said we have to quit meeting like this.
