I think that yours is above mine with science, although they are interested. I have my own surreal moments, though. I get strange things like how when my oldest was about 6, we passed a graveyard and she couldn't stop crying, imagining all of the bodies under the ground. Each time we subsequently passed a cementary, she had a million questions about life and death and burial. I asked a friend if her kids asked about these issues, and she smiled and said "we live near a graveyard and my kids have never asked one thing about it, I think yours are...unusual". Oh, OK.
