When I was younger, I had a lot (and I mean A LOT!) of Legos, and I would build these extravagant, multi-bedroom houses with them. I also had a collection of beads, and I'd pretend that the beads were a family living in the lego house. The storyline was always the same: there was a 16 year old girl, she was the 'mom' and she had a husband and like thirty bead kids. I would make them go on pretend talk shows and try to convince the audience why this was an okay set up. It never occured to me that a 16 year old girl would not be able to be biological mother to all those kids.
