I know what you mean Liz.
My dad's parents got divorced, so she married another guy and he had like five million other wifes and kids.
So on christmas day when we go up to my grans house, there are hundreds of people I am related to that I havn't seen.
This guy came up to me and was like, "Hey Cal, I havn't seen you in a while". I was like :Who the frigg was that?"........it was my uncle!!
Then to top it all off, I have tons of "Step" relations which are snobs and they **** me off so much!!
