Frugal folks come from all sorts of backgrounds. Some were raised in typical American families with traditional buying and spending habits and came to embrace frugality much later in life. Others were raised by parents or grandparents who made simplicity part of everyday life — from the way they cooked and cleaned to the way they fixed their cars and celebrated holidays. For those of us in the latter group, we can spot another member a mile off. There’s a sort of unspoken but common shorthand that comes from years of shared experiences. What follows is my tongue-in-cheek way to tell if you were raised by frugal parents (or if you might be on the way to becoming one yourself).

Though these signs are offered with a bit of humor, there’s a grain of wisdom that guides each. Our modern-day mantra of "reduce, reuse, recycle" is just a new spin on an old refrain. For many of our frugal mentors, there was simply no other way to live. The tips and tricks they taught us are recounted here with as much respect as comedy — and with a gratitude that comes from rediscovering best lessons of our childhood.
