know it all vent

Has anyone ever had one of those friends that think they know everything about everything even if they have never gone through it before. I have a friend who is getting married and buying a house and any advice I try to give her since I have been there and done that she shoots down and tell me im wrong. Then when I try to tell her the truth she says subject change. Buying a house is a big deal and there is always tons of hidden fees and things you need to know when buying a house. She completely disregards anything I say as nonsense and basically makes me feel like I have know idea what im talking about. Anywho thanks for letting me vent and get out my irritations. Shes just be so under my skin for the last few months.
