Today I rescued one.
I'll count that as a good deed. I picked her up and got her away from someone who went all "A SPIDER A SPIDER!" and was flinching away from said spider. Spider was safe, spider-phobic person was safe, I was safe (spider-phobic person didn't hit me for not killing the spider, either!), all was good.
Which reminds me: a few weekends ago, my 9-year-old relative Markus tried to freak me out by putting a spring-loaded fake spider on my shoulder. (You squeeze a bladder and it hops.) I not only didn't freak out, I was saying, "Um, is there something alive on me?" and being careful how I moved in case that were so.
I've also had a long, long snake (I forget which species, but obviously not a poisonous one) around my shoulders, so I don't freak out about snakes, either. Hey, I need some superpowers...
