Translation of Heißluftballon

Vivi, Sabina and I wanted to thank you very much for Sabina's gift! Thank you for the cool outfits that she is now wearing, all little boys are waiting in line lately. I wish you much happiness.
I have sent you the translation a few hours ago. I guess it has just arrived. That is very responsible of you. I will have a look at it immediately. If you want to address somebody formally in the singular, you must use 'usted'.
I've lived a year with my wife in Argentina, and that is why my Ppanish is actually quite good, but that's not really enough... I wish you a beautiful day and a happy New Year.
