Not a good NSV

I love Yoga but now I have to buy a thicker mat.  I didn't know until now that I have a tail bone and that stucker hurts when you sit on it. 

Lol!

Yeah, I have to take a pillow to my 2.5 hour (academic) class, where I have to sit on a hard wooden chair.  I need to use it for car trips longer than about an hour, too.  I actually use a small U-shaped neck pillow facing with the opening in the back, so my tail bone is over air.
