No, not that D-Day... i mean David Day!!!
Happy Birthday, squire!
(I'm not a sentimental person so i would never tell him how grateful i am to have him as a friend, or how grateful i am that he puts up with me and listens to my silly problems when he could be out playing. I wouldn't dare.)
On the other hand, he could just read this.
David, have a good day and fill up on cake, okay?
This is Mallory by the way.
