The gnome takes the cup, and tries to do his best filling it without spilling water over the edge. Which is quite hard, as you can imagine. "I am sorry, I don't have any wine or other drinks except water. I didn't know that I would have visitors... I do have bread and meet with me. Maybe thou wishes to taste something?"
The gnome takes a big bread and some meat, wrapped in cloth. One of the several papers in his bag pops out, and you notice big letters in an unknown writing... Gnomisch writings? Then you notice the several black spots on his dark fingers, ink.
The gnome follows your eyes, and explains "I have just finished some notes for my journal."
