If you are asking what you would write, here's what I would write
Dear (Friend's Name), today has been an interesting day. Have you ever tried talking to your animals, because I just saved a puppy and it started talking to me. I am not kidding, he said his name is Derick the Third, and he is a nigerian prince. If you want to come check him out, try and come by.
- Sincerely (Your name)
