... I came back from grocery shopping to a message from the seller and an email note from the stud owner. Other than my needing to call the vet in the morning to get them to send the health certificate out, all is well. No one said "that date/time can't possibly work!" So, whew.
Now I can instead concentrate on preparing the house for an impromptu party on Saturday occasioned by visitors from the East Coast. Whee!
