Here is my problem. I'm from France and live in Ireland. Every year, i go back to my grandparents when my sister is there with my two nephews and my dad joins us. the timing is dictated by my sister as she's the one with the kids. only this year she's picked a time of year when i won't be able to fly. dad is asking whether or not i'm coming but i'm only seven weeks and not ready to tell them i'm pregnant. any ideas on how i can put off giving him an answer or think of a good excuse? or should i just come clean?
