Verb conjugation of "streicheln" in German

I will send you a summary of the activities from our last vacation last year, but I will be brief, so I will send only the highlights. It is best if we discuss everything, in the beginning of August.
My correction were added and highlighted with yellow markers and attached to this email. Tell me now if you have any questions about grammar rules, since I was a teacher 10 years ago.
Many thanks for your suggestions. They are very useful. I can't answer your mail now, but I will come back to you later when I'll have more time. I hope that you and your family are well!
