Idk if it bothers people but I feel like if you know me you know it’s a sign that I’m bored. I’ll do it on tables, steering wheels, walls. Really any surface I can find that can be hit with my hands.
Sometimes, if my cat really wants my attention, he‘ll grab my leg loosely and bite me, where it hurts for a bit but leaves no mark nor blood. It’s not quite fun- but I think it serves a meaningful place in life
