I know what you mean! It's not that my hair even has all that much more wave in it, I don't think; more like, it's more consistent and defined and less poufy. But in my mind, there are "real" curlies/wavies (the ones who have curls no matter what) and then imposters. And I feel like an imposter sometimes.
But it's pretty irrational, because like I said, if I don't have wavy hair, what do I have? Just awkward bendy hair, I guess.
