If you have ever gone to a garage sale/flea market looking for bookshelves, etc to turn into housing or other accessories for your ball pythons.
If you have ever made yourself leave your wallet/purse at home when going to a show to prevent overspending, only to discover you "accidentally" stuck a credit card in your pocket, and after all that is a really good deal on that morph you've been wanting.
If you've ever gotten your feathers ruffled by an unthinking non-reptile person while in a pet store, and gave them a bit of education in a not-so-polite way because you are sick of snake haters.
If your spouse has ever changed the channel because you keep talking over the commentary on a "reptile show" on TV, loudly pointing out the obvious mistakes and misinformation.
If your spouse has ever come home from work and asked, "When is dinner?" and you reply the rats aren't thawed yet. Then you remember the people in the house need to eat as well as the snakes.
