Centaurs are very social creatures, which means they have to rely on each other for various grooming. For intelligent beings, this is the perfect time for some socializing. Shirleen is making good on a promise to work on Cubist's tail that she mentioned in my comic: (http://offcentaured.com/comics/69/)

Cooper is letting his man Siege straighten out his tail.

Happy centaurs enjoying a day out in the sun, what more could you ask for? :)
