Cenae Latinae
Thanks to Briana, I wrote to find out about the Cenae Latinae (Latin conversation dinners) which apparently happen every month in the Bay Area. That would be lots of fun!
Mr. Bad told me that there were also monthly Esperanto dinners, but then he went on a cross-country trip and didn't take me to any of them. It would be confusing to switch regularly between Latin and Esperanto conversation dinners, what with the closely related vocabulary. "Salvete, amici, mihi nomo est Seth, atque in regione Missionis mi habitas. Mi amas veni ad has cenas, cxar dicere kon vobis omnibus auxiliat mihi, ut mi lingvojn facile loqui lerni povus. Vos estas la optimi!"
I heard back from the Cenae Latinae folks, and they said that the next dinner was this very evening (Saturday).
