Should I be frightened?
Toby bites, mostly (I thought) experimentally, thoughtfully, absent-mindedly. But lately, when I shout NO BITE! (why DO we talk Tanto to children?) he pauses to consider, looking deep into my soul before... laughing. It's a short little Hum of a laugh, almost a reverse-sniff-through-the-nose laugh, like an overworked IT guy hearing a joke he's heard before.
Can an eight-month old be sadistic?
