I do!
I must tell you: You are not alone, I also read all the books I could get at the local library that dealt with Greek mythology as soon as I could read a bit.
But I devoured Harry Potter, too.
And now I'm studying Latin and still reading fairytales and myths from all over the world, I haven't grown up at all. ^^
Aha, growing up is overrated! :D Also I love that you love sea cows - the rest of the line my username is from is "why do cows fall out of the sea" :')
