The worst thing I experienced when my boss learned about my new hobby.
He: "So what's that about your new hobby?"
Me: "I started collecting tarantulas, why?"
He: *raises a brow* "Aren't those poisonous?"
Me: *10 minutes quick education about the difference of poison and venom* "So you see, nope."
He: "Well, I only like them roasted" *smiling and trying to change the subject after that*
I know he was joking about that last sentence, but I also know, he's not a fan of ANY kind of pet, too. So I don't take offense. I'll just have to get some new T delivered to my working address at some point, preferably some bigger specimen around 3" - 5" and see what happens
