I've heard sooo many of the comments in this thread too!
The one that got to me the most was someone close who said she was really excited for us because life without children is meaningless. 2 years on, no children, we're still trying & she's repeated that comment many times.
Funniest I had was my BIL who asked when I was due (had to give him a bit of an IVF tutorial!)
Weirdest was a friend who kept insisting I make the doctors transfer 2-3 embies because she had always dreamed of having a friend with triplets!? And she was deadly serious!!!
