My most annoying habit are;
Biting my nails very often
Having Sequoias itch over all of my body(have diffcult with itching, it won't stop, it does drive Sequoias crazy because he have to do that EVERYDAY)
my body moves like, leg, etc that people would ask if Im nervous
Playing with my hair when it's long.
Cracking my fingers or neck or back very often
I only can think of that so far
