In the car, in my purse, in the bathroom, next to my laptop, yep, another floss adict here! My son laughs at me because I don't go anywhere without it!
My dentist still gives me the "You need to floss" lecture though!
I am a big flosser also, but I carry the sticks because the pointy ends come in handy for all kinds of things like removing splinters, changing time on analog clocks, piercing cellophane wrappers, etc.
