I just heard from Erin. Seems she TOOK Bearlish in college, and though she is a bit rusty (her words, not mine) she thinks this is a fairly accurate translation or Borris' message:
"We are so glad it's spring!
What a long winter. Is anyone else famished?"
I'm going to remember that Erin has this gift and will consult with her for all my future Bearlish translation needs.
