Since we can nominate several threads, here are mine:

The Diary of Eduardo - I like all the diary entries, but this one is my favorite

Looks like I'm a foster mom

Pet Talk Confidential - 5th edition

Professional Tortellini Sleepers - this one is really great

Dear Edwina, I can feel your pain - Juni's story

I also liked many of the threads nominated already, but I wanted to nominate these
