I work with crazy people, and violent people, and people "in crisis," and I'm not allowed to sedate them. I don't normally get scared of them. I've been assaulted so many times I've lost count, but I find most people, even unpredictable, violent, psychiatric people, are generally decent if you're patient and you have a sense of humour.
ugh - I hate spiders too. Living things should not be that creepy.
