I'm not 100% sure. My brother has seen me do it twice and he's ESFP. Both times he thought I was losing it. I hope it's an iNtuitive thing because then I have an excuse. Otherwise, I just look like a nut...So this is an N thing?! *relieved sigh* I do the same thing! It's so good to know I'm not crazy-crazy, just iNtuitive-crazy.
