I know dating a co-worker can turn ugly. Me and this female co-worker like each other. I'm 24 and she's 31. She has no kids and has some college education. I'm currently in college and soon to graduate. For some reason I think this wouldn't work out for a number of reasons. Our age and if it gets serious, I don't think she wants kids at age 33 and so forth. Now, I want kids. Another problem is she showed me her sisters one of which is very cute and two years older and thought about asking for her sister out instead of her. Would it be weird if did that? What should I do?
