JWs: what did you do when someone just wants to argue and not reason from the scriptures?

[Tears In Rain]

If you encounter a person who no matter what you show them in the bible, or tell them the bible says, they still just want to argue, not reason it out... what is your reaction? If you end the conversation or remain silent, is that right or wrong?

I'm asking because this has happened three times to me this week and i am still learning.
