Hi Captain Arnold,

Thank you so much for the package! The photo is beautiful and I actually have it framed now. And what a beautiful and unexpected memento to have a copy of our vows.
Thank you again for your wonderful ceremony and service. I will genuinely and sincerely recommend you to anyone who asks. I hope this finds you warm and well.

Best regards to you and your family,

Daisy
