Who is who?

So I tried to find pics of them both to see the difference and these are the two best that I could find. Small pics but can you tell who is who? Yea I know not hard to tell some things are a dead give away but I still think they look alot alike!

Here are frick and frack as I like to call them. We had tons of fun with Susan & Hattie here. And gus too! But when Rylin and Hattie got together it was trouble. Susan and I couldnt take being in the house with them for more than a hour. We had to get out everyday and go somewhere to wear these girls out. We went to swim almost everyday and tried to find different indoor playgrounds to go to since it was way too hot to play outside. The day that Susan left Rylin woke up that morning and went straight to their room looking for her partner in crime! It was kinda sad when she realized noone was there. She was even checking under blankets. Too cute! I came down to Miami that same day because Matt and Chris left for Orlando so I thought it would be fun for Rylin to play at Grandmas and Grandpas house. Anyway Rylin and I both miss our playmates. It was a blast!
