From there, do not hug him anymore. If he attempts to hug or touch you, back up and make it clear that you are uninterested. It could be that your co-worker didn't realize his strength. It's also possible that he has an interest in you or that his behavior could be headed toward harassment. If he does anything else untoward, take it to your boss.
Q.: I have a friend who constantly comments on how I spend my money. When she notices that I have bought a new dress or that I got my hair done, she asks me how much it cost. Then she makes nasty comments about how I spend too much money on things. I have a good job and can afford my lifestyle. She is a single mom with a low-paying job. What can I do to handle this better? – Uncomfortable, Racine, Mich.
A.: Stop answering your friend's questions about prices. She seems to be living vicariously through you. To get her to snap out of her vicarious reverie, you may need to tell her that her running commentary on your possessions hurts your feelings.
