Being new at work, how many times would you try to relate to an unfriendly coworker?

'relate to' isnt the word I'm looking for but I can't find a better one right now. Being new, I feel like you have to/should try to make yourself known, and mingle with the folks who have already been there years, as they have probably seen many new faces.

How many times would you try talking to unfriendly co-workers.

I still like my job and am so glad I have my own office. I get to pick how much social interaction I want
