I actually had an assignment similar to this one!!! I attached my essay...hope it helps!!!
Translated: My friends are Peter and Whitney. They love to make fun things. Peter and Whitney are very sweet. We have been friends for many years. They are brother and sister. We are best friends. Hope this helped!
I would add me gusta and no me gusta before the ones you like and don't like. Gusta means i like and no me gusta means i don't like so you will be golden!!
