It's a Terribly Bad Habit.

[Suicune's Fire]

As for me, I pluck my eyebrows, but that's mainly if I'm terribly bored or just want to remove the loose hairs so they don't drop into my eye or something like that. Also... I pick my nose, BUT WITH A TISSUE, NOT MY BARE FINGER. I also do it in private. It's mainly to clear out the rest of the gunk that you wouldn't normally get out just by blowing. That and I always wash my hands afterword, or at least use a hand sanitizer.

Neo do you realise you're listing basic hygiene practices? xD Sillyyy

I still bite my nails. But only ever to straighten them out; I don't chew on them. I have a lot of other habits but they're not terribly bad I suppose haha. Although I do have a bad habit of constantly staying up late, even when I have to get up early.
