I'll share about my experience as to how I got my parents to understand me. Like Tyler said, i dont know your parents, so DISCLAIMER: results may vary
Anywho, I started thinking about this idea of prepping after much contemplation. I took into account many factors that were shaping the new America, and began to realize the path were on is not a path that one can simply come back from should it not work. Like in a video dr Henley suggested, the economist said that there was not one nation in history that was able to survive indefinitely off of a currency without real backing. I agree when the economist says there's no indication that America should be exempt.
So there's the reason, the country is on a sketchy slope and when we slip, we're going to fall to the very bottom. But how to describe such a belief to your parents? Most parents are going to be freaked that their kid is capable of thinking somethin other than they've been taught, but that doesn't make you crazy. I took a very similar approach to Tyler, and tried to ease my parents in.
My dad wasn't too hard to convince, being a farm boy, the thought of finally getting to teach his sons some skills like hunting and shooting made him happy. (And an excuse to buy some more toys) I don't believe that my dad is on board with the rationale of my desire to learn, but he doesn't seem to be bothered by it.
Ok, one down, one to go
My wonderful mother, a suburban girl, was on board with my rationale, but was very hard to convince that it was worth actively preparing for. She is very understanding, so she doesn't seem to be bothered by my prepping.
Now, with the background and a brief explanation of their reactions, I can explain what works, and what doesn't.
Generally, watching DDP on nat gel will yield negative response, those people are kinda nuts and give all preppers a negative connotation, not what you want your parents to think about your new life choice. They do occasionally have good ideas, but I wouldn't use it for reasoning purposes, I did not personally try this, but this is my rationale for not using it.
Things like Oakley sunglasses that are ridiculously expensive are sometimes good things to drop hints with. "Geez mom, can you believe people pay this much for sunglasses?(though incredibly durable) wouldn't you rather have like 100$ worth of food or water stored for an emergency? Sunglasses will look nice, but it won't do much in an emergency..." Generally positive if you throw some humor in, and can make them think of some unnecessary expenses in their own life. Maybe more for you to use if you get them on board
I've heard numerous accounts of teens taking the initiative and parents give a budget to them in order to prep for the family.
Play to what they want to hear, but do not lie! Recently we learned in depth about the Lincoln Douglas debates of 1858, Lincoln was a master of focusing on different parts of his view on slavery. Focusing on his belief in unalienable rights in the northern debates, but shifting focus to his belief that slavery is not to be affected in The states it exists when in southern debates, but he never lied. Try shifting your focus on different points of prepping to different situations in order to use them most effectively. Similar to me playing to my dads desire to teach me hunting and playing to my moms understanding by presenting rationale with facts and logic.
I hope some of these help, I typed this on my phone so hopefully the mistakes aren't anything unbearable, i double checked it real quick. I hope that any teen that reads this understands they aren't alone, and you don't have to become some weirdo in order to prep. I'm a relatively normal guy, i still have friends, i still run track and win some races, I keep a high gpa... You don't even have to seem like a prepper, in fact it's better to be the gray man, the one nobody would expect to be a prepper. Thanks for taking time to read, and remember to stay classy. Always.
