Verb conjugation of "backslide" in English

Everyone says, that I am sending always silly pictures, so here 4 more images. Your picture is very cool, especially the hat, it has a really cool shape. Are there different sizes?
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.
I would be pleased if we can still keep the contact alive. In the future I will have more time to write emails in Spanish. At the moment I just can't. Sorry for being so direct but this is the truth.
