"Tongue in cheek"! I heard that people would really do that in medieaval times and that was where the expression came from!
Alexei certainly was a very specific sort of boy-- he wanted everything just right, even if it meant hitting a companion! To me, though, it looks like he's just lightly slapping the little boy-nothing too painful, because Alexei was kind, too.
Btw, Avril's Innocence is great song to me.
I like it too! Not many of her other songs appeal to me--I've only heard a couple more, though, but this one is so fun. I like that you can hear the lyrics, unlike a lot of modern music.
