Do you find it a bit odd that your co-worker asked you for relationship advice? I do not think that is a topic that I get into with my co-workers. Our conversations are normally very generic. They actually are pretty fake since they are so general. The least that they know about me the better things are and I am sure that they think the same exact thing. I would probably be thrown off kilter should one of them ask me how to get over a break up. I would probably just stare at them trying to figure out why they were asking.
