I have an adult female who is like this AT ALL TIMES
my cousin and friend steve were over today and I let them handle 2 of my boys and steve was like hey whats in this drawer? and I let him investigate and she was sitting in striking position hissing. he jumped back so fast haha I was laughing my a** off. usually once you pick her up she calms down immediately so I grabbed her and was standing next to my cousin mike and she was flicking her tongue and behaving then out of nowhere she starts huffing and strikes at his arm hahahaha I love her attitude. but yeah idk how your snake usually behaves so it may be a completely different situation...
