You have wayyyyyy more patience than I do!! Whenever my hair grows long enough to sit on, that's my cue to get it all cut off (to my shoulders or ears) ASAP. My hair grows very thick, and very fast, and thrives on neglect. I only realise how much of a literal burden the weight of it is when I get it cut off - it's SUCH a relief. I always intend to keep my hair short, or at least shoulder-length but somehow I usually forget until it's grown down past my hips again. It's a terrible cycle.
