Happy birthday,
dear
haltlos!
I hope you've had a wonderful day so far and that what remains of it will be even better. :) May there be lots of presents, cake and dear friends around you!
Here's a little present for you, for your exclusive use (unless you decide you want to share):
We haven't known each other for long, but I know you're a caring and generous person, and I'm very glad that we have met. Have yourself a great birthday, dear. :)
