Differently Ethical
I would find it difficult to say that.
A colleague was rude to her once and she went batshit.
I now have a plan though - she freaked out when she saw the office mouse and went and hid for hours, so the next time, all I need to do is say 'LOOK BEHIND YOU! A MOUSE!'
Then I would say "Sorry, but do you mind if we chat later? I really need quiet while I eat - I know it's silly isn't it! I'm always been like this since I was little" *apologetic smile*
Whenever else she tries to chat to you, just try some variation on, "can we chat later? I have an awful headache/am really behind on my work/had some terrible news today and want to be alone. I'm really sorry".
If she is like me, she will respond to polite firmness. This isnt rude. Tempting as it is to feel like saying "pi$$ off"

) but he still doesnt get the message. 
it's not like we can chuck him out like we do with distruptive students.
