Something I think everybody has missed out on and is important is that in going to a family function such as this you are able to see her and her family under a microscope. So any under lying mental craziness that she has been able conceal when it is just you and her is definitely going to come to the surface at an event such as this. Nobody can hide their true selves when they are with their family. There is such a history there that any trait that is possessed by your girlfriend or by her family, whether good or bad, will definitely come out. This will give you a good indication of whether or not you can deal with her little quirks or whether they drive you nuts. Either way, it is better to know now about any issues - personal or family wise- that you can't handle.

Also, you may find out that this girl and her family are awesome.
