Two headed child

I have been best friends with Lisa since we were in second grade - we grew up together (and are still growing up together). Last week when Lis told her father I was expecting he reacted by laughing: "I remember when you were kids and talked about having babies," yes, another I remember story - I'm becoming more and more fond of those, "One day you two sat in the back of the car and for nearly 30-minutes Amber (me) explained why she wouldn't want a two-headed child."

I remember this conversation in the back of the car. Funny how things work out - I may not be having a two-headed child (thank God) but I am having 1 birth with two heads. OK, re-reading that it sounds a little gross, but you get my drift.
