You know you might be a prepper/survivalist if you:
Overhear you daughter instructing her brother on the best method of removing spines from an edible cholla (cactus) bud.
Send the kids out to collect lamb's quarter, purslane and mallow 'cheesits' for the dinner salad. And can be 100% confident they will pick from the right plants.
Be in the midst of shopping and have your DD whisper to you, "I think we should buy more honey so we'll have enough when there isn't any food in the stores."
Buy enough steel bar to secure every vulnerable window in the house. But be ready to tell the DH, if he finds the bar, that it's just for securing chicken wire plant cages or for staking trees.
Have one of the checkers at the hardware store, where you buy your canning jars, ask if you want to sign up for a special customer card because, "You are in here a lot."
Beg your DH for a Lehman's stove top oven for your Christmas, anniversary, birthday present, and then hope no one at his work asks, "So, what did you get your wife for Christmas?"
