Translation of hinterher

I would like to know if Jack is interested to join us as well. Shared learning is called Tandem. I'm coming in 2 days to Spain. I will pay for the study costs of my daughter, and I assume all other costs as well.
Somehow, my email was not sent. There were even a few mistakes, but really only minor things, nothing really bad. I've already read some other texts that you have sent and are getting better each time.
Do you speak three languages? Wow? I'm sorry that I am writing to you just now but I have a lot on my mind at the moment. My daughter had a cold and the nanny, too. I needed to stay home.
