While the guild may view a valid use of them signing paperwork, I must admit I disagree.
I could be using them to lift a glass of mead, to hammer out the dents in armor and weapons, to make tea, to eat lunch, to buy a new pair of shoes, to train squires, to bake, to bathe, to set forth our next plan of maneuvering for the guild, to obtain a ticket to the gala, to have far more interesting conversations on the network. Faram even brushing my teeth might be a better use.
Or perhaps, to give you a back and shoulder rub after such a long, and tiring day of practice and carrying around that lute case, no?
