Really? Over here most boas are considered very docile. If handled regularly even aggressive adults and imports can become gentile giants. Common Imperators are very popular pets, even for older children (my grade school teacher had one in her classroom, and that's where my fascination began), due to their generally lazy and docile nature. The Boa C. Constrictor and Boa C. Occidentalis sub species are more likely to display moodiness or occasional aggression, but even they are well behaved most of the time (I find that if they've eaten recently, they're usually in a good mood, haha).
