In HR do you have to be a people person?

You know what i love my job, i can proudly say that i am a true HR professional, but one aspect of an HR professional and probably the most important is the attribute or trait of being a 'people person', isnt it what most freshers say when they want to get into the footholds of the HR profession..i am a people person...and i love interacting with people.

if that were the case even a marketing person could become a HR professional coz well hey its not like he was even dealing with monkeys or primates,..he after all is dealing with people....

so my question to my few but limited followers, is do you need to be a people person?

cant wait for the answers...
