I think she is just letting you know that if you straighten it, it'll look longer. That's all.
Try not to take that personal. Logically, it's true, if you straighten it, it will look longer.
That's one disadvantage we curlies have, I guess. But I'm willing to live with it. If I want my hair to look longer, I will have to grow it out even more so than a straight hair person. Oh well.
Short, curly hair is cute. So, enjoy it!!!
That's right, I said it! I wear scrunchies!!

I am a sulfate washing, cone slabbing, curly lovin' s.o.b. The CG police haven't caught me yet.
