The Missing Piece Meets the Big O, in fact.
The other day my daughter laid her hands on a Disney Princess Magazine while I was paying for our groceries. It took her just those few minutes to understand a plot in which both Abu the monkey and Raja the tiger meet and fall in love with a sexy-lady monkey and sexy-lady tiger. This adding fuel to her romance and marriage obsession. So now she's making up stories about Sebastian and Flounder finding hetero-normative love interests too. She asks me daily for stories about how her dad and I met, fell in love and got married. She talks constantly about wanting to marry her best friend (He's sensible enough to not be into it, as "I might meet someone I'd rather marry by that time!")
Anyway, I know the marriage thing is normal little girl stuff, and I can well remember my 4 year old self's plans to marry my cousin (we were going to evade the authorities by living in a tree house), so I'm not actually alarmed, just maybe it would be a good idea to do a little book shopping.
