Translation of Schriftstück

Luckily it didn't happen to me, my kids really grew up with us all the time. And besides, they are not allowed do that, because they are monitored endlessly. If they don't attend class they could find themselves on the next train going home.
Thank you for your email! A little question about yourself. How old are you? I think the Americans are using the word color and not colour, but I understand if you are not sure about it.
I would also like to thank you for your interesting phone call on Friday 4 weeks ago. As you have proposed at that time, I will bring up a few ideas for possible cooperation in the future.
