Who is responsible for tracking down those who have not RSVPed? Most of the guest are coming per request of my mother or his, (I have met five of his thirty guests and he hasn't seen twenty of the remaining twenty five for more than ten years), so I feel kinda over-whelmed with the idea of tracking down people I don't know or like on top of everything else I need to do. I know it sounds selfish but it is my wedding and I am paying for most of it so shouldn't I get a bit more respect?
