My friend said I looked like a Golly Wog?

She has been your friend for 11 years. She didn't mean to offend you, she was just making an observation. It's like when I told my former girlfriend that she looked like Coolio one morning after she just woke up. She wasn't offended (though she didn't find out for a few days exactly who Coolio was or what he looked like; but she still thought it was funny).
