Is it wrong to want to separate personal life from work?

To be honest, you are smart to keep your personal life separate from the workplace. The gossip gvine has ruined many a career - I've seen it happen MANY times. It seems to me that you are trying to 'fit in' with the other guys and brag about ual conquests and such. It's a dead-end. Just do your job. Your personal life is not part of the workplace.
