Lol I can be pretty calm with some of my snakes, but when it comes to feeding time I ALWAYS JUMP! It just makes me jump a little, even when I know the strike is coming. I try not to jump, but I don't ever jump when feeding the colubrids. The pythons and boa is what really makes me jump.. You think they will strike when you count to 3 but they end up doing it before you finish counting and it startles me lol. I guess the colubrids do it in a more calmer and expected way then the pythons and boas.
