In May I'll be able to show the machine at an exhibition in the university. In addition, we can show it to all these university partner laboratories in the U.S., which are led by people who live here.
Sorry, I did not know that I have a meeting with a friend. I will talk about our trip. Many thanks for the email and I hope we write eachother again soon and next time longer letters, I promise.
What are you doing? I'm at work. It is so boring and my boss is not here. Yesterday I was here until midnight, because we had problems with the PC system. Then we ordered pizza and a few beers.
