Some will, some won't. In my experience, they are pretty calm, even in the wild. The adult female I have is now one of my "kid education" snakes, and I have only had her a little over a year. She was puppy dog tame from day one which surprised me, since the landowners had "caught her in a bucket" when they asked me to come remove her. Expected her to be a little ticked when I opened the bucket. She just kinda looked at me like "can I get out of here now?". So I picked her up and talked to the people about what she was and how she was harmless. They touched her and stuff and then I brought her home. She was a sweetheart the whole time, and still is.
