Verb conjugation of "wahren" in German

I will be visiting in Italy from April 10 to 15 in order to meet some old friends. I'd like you to attend a one-day course, maybe I can help you in learning something new. Please give it a try.
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.
In school, we now are learning the grammar part, more specifically, the participles and so on. I understand it at all, but the conjugations, boy they are tough. A lot of patience is needed.
