Antisocial

At work I keep to myself I keep my conversations work related and nothing more I sit in the corner by myself and prefer not to mingle with co workers or chat with management. Today a co worker was upset because I wasn’t being chatty with her and the other staff but nothing against them I’ve just always been this way I don’t attend work function or engage in work activities. It has worked great for because I prefer my coworkers to be just that I like to have as little people as possible know me. I’m not antisocial I just don’t consider work a place to make friends or conversation. So now this co worker gets all upset when her and I are on the same unit because I’m not “chatty” I’ll listen to her talk but I don’t add any feed back of my opinion I just say right and ok and yea I understand. Anyone else this way
