Translation of ultraviolett

We would love to have you here as our guests! My niece Katja had also many diffculties with the new surroundings. She is really upset with this new change. How was your trip to Italy? I'll keep writing to you!
On Friday, I can send it from the US. But I would send it from here with EMS or even better with UPS, including delivery confirmation and tracking. From the US there will be no return address or tracking.
Usually I do not care too much about not getting change, but when you pay a 3 dollar ride with 50 dollars, you do actually expect change. We stood there for a while and neither of us knew what to do.
