Oh, I think you'll get over it, Julie. Somewhat.
As you pass the other milestones, second letter, deposit & date, payment in full, plane ticket bought or travel arrangements made, you'll shake your head that you made it this far.
I bet you'll have all that stuff done 'WAY ahead of the actual date, and be left with the date creeping up on you all too slowly

The monster grin will go away.
But the 'Mona Lisa' smile won't
