Should A Guy Ask Her Family's Permission?

A lot of traditions have come and gone, but with the recent buzz about Kim K's marriage and the details about both the wedding and proposal, one question has been asked of followers of the story; should a man ask his girlfriend's family (mainly her dad or mom if dad is not in the picture) for her hand in marriage? Would you want your boyfriend to ask your family? I happen to think that this tradition is a nice one to continue. I think if you're a close knit family and your significant other asks your family for your hand in marriage, that would really bridge the gap. It shows how much he cares and how much respect he has for you and your relationship with your family. His including your family in such an important moment also leads your family to be more open to accepting him into your family's circle. On the flip side, it may be something you want to be between just the two of you. Perhaps you're close with your family, but want your engagement to be something you can share with them at a later date and if you're not that close with your family, this might not be such a good idea. It could also be a very embarrassing or uncomfortable situation if the guy asks for your hand in marriage and is told no... Hopefully that wouldn't be the case though, but what do you think? Should he ask or should this tradition be dropped?
