Translation of Umschwung

I hope you you had a successful week in Dortmund. Because of the bad weather at the last moment I could not get on my flight to Dusseldorf and I have stayed home. I was afraid to fly.
I met the company last autumn, because the site's traffic is getting pretty big and they invited me to a workshop. They have convinced me that I have to put their logo at the top of the page to maximize exposure and this was a big mistake.
I do not teach Spanish, but geography and history at a school here in Frankfurt. It is good to live for a year in another country. I would be glad to receive a picture of you.
