I had stick straight, super thin hair when I was little. My mom kept it short and permed because my scalp kept burning otherwise!
I started trying to grow it longer in 4th grade, and by 7th grade it was nearly shoulder length - and starting to frizz. Not curl, just frizz. I tried to wear it curly in high school a few times, but mainly ended up with crunchy gel-covered waves (a few) and lots of frizz. I had a big chop in college, and it went curly then. Now it comes and goes, and I have about 3/4" of nearly straight in the middle of my spirals, because every time I go on antibiotics (and I did in January) the hair which grows out at that time loses the curl. I'm sure I'll lose the curl when I get older, just based on the rest of my family.
The pews never miss a sermon but that doesn't get them one step closer to Heaven.
But at least the pews never attend yoga!
