Verb conjugation of "zittern" in German

This is not so easy, my dear! Unless you have learned Latin, then Italian is not an easy language... I'm new here, I found the site through Google. How does it exactly work here? I want to sign up.
I am sending you my e-mail address. Then I can write in German and send it to you faster. Please send me pictures of your children. I love little kids, they are always so sweet and innocent.
Thanks for your help, I was on holidays in Galicia, it was just beautiful, I had a long weekend, and have taken off for a few days. And what did you do on last weekends? did you stay home?
