-Ren's a good friend to have and she's terrible at it, but she tries to comfort people. She would hold their lil bean hand and do her best.

-If by decorate you mean cover the house in shiny rocks, leaves and seashells + graffiting the home, this girl can help.

-As for the food issue, Ren can also help. She's been introduced to things like candy and the like that are just delicious and fun to eat. She could share these treasures with them.
