I’ve only had my hair long twice in my life because my coordination issues made it nearly impossible for me to manage a ponytail.
My most recent experience with long hair had my younger cousin giving me a very specific tutorial on how to put a ponytail in. (He sat on my lap and reached back, giving me a hand-over-hand type experience.) It was difficult, but I got it.
(Since then, I’ve learned that hair clips are easier for me to use than ponytail holders.)
