Do I run my fingertips over things with a thick texture? Yes. It's something I did more when I was younger however. I'm not sure if that's because I seldom find objects with rough textures or because it's something one grows out of. If I have to inspect the bottom of my shoes I usually will run my finger over the tread. 

How frequently do you find yourself making your RP character do something that you don't want them to do, but it's in character for them so you end up doing it anyway?
