My MIL told me over 2 months ago that she would be working this Christmas day (she's a nurse), so we have arranged to have Christmas dinner with my sister, her DH and my parents. We had them all over including my PIL last year (so was thinking it was someone else's turn anyway)and being 24 weeks pg it will be nice to sit back this year. My SIL called yesterday from Australia to ask why we were abandoning PIL to have a cosy Christmas with everyone else!!!!!
