Getting married

I know everyone is tired of hearing about this but I am getting married Saturday. My question for you ladies is when did your family met your SO's family and what was their reaction. Mind you we are from two different worlds in a since my family and his family understand that. I am nervous that our families won't like each other. Everyone will officially met today, well our parents will met today!! I'm nervous and going crazy thinkin that something bad is going to happen!!
