How do skeletons send mail geometry

I think there may be a bit of confusion here!

Skeletons, being inanimate and non-existent entities, cannot send mail or engage in any physical activities, including geometry. Geometry is a branch of mathematics that deals with the study of shapes, sizes, and positions of objects, and it is not related to the actions of skeletons or any other non-existent entities.

Additionally, mail is a physical object that requires a physical entity to send and receive it. Skeletons, being non-corporeal, do not have the ability to send or receive mail.
