I know it's impossible. But Bill, I've been through this message to invite you to be my date at my prom. It is a very important phase in my life and I would like to have you present.
It is a sincere request, I Know that it impossible, but I count on your presence.
I'm kind of confused about this, but I'm sure I need you next to me at graduation. But I understand if you do not want to attend. Thank you for everything!
