There is nothing more endearing than seeing true friendship and love. Especially, if it as improbable as that of a big dog and a tiny kitten. Somehow, animals feel when they are dealing with a baby. For example, no matter how much a toddler will tug on the tail of a cat and play roughly with it, it will never or very rarely fight back. This set of pictures taken by Jessie Pon shows a tiny kitten mistaking an adult golden retriever for his mother. Though it may hurt the dog’s nose with its sharp claws, the dog does nothing to harm the kitty. On the contrary, it’s watching over the kitty-cat as if it were her own puppy. (Photo by Jessie Pon)

Each day as we look in the mirror, we think that we know ourselves. We are used to the image that we see before us, but the mirror can show us much more than we ever hoped to see. Sometimes it only shows basic emotions, while at other times it can highlight the deepest crevices of our soul. If you wish, in the reflection of the mirror you can see your deepest thoughts, masks that you wear every day, your desires, and of course the people that you think about. But are you brave enough to look deep within your soul? Will you dive headlong or shy away from your true image? Those that will muster up the courage necessary will realize it was well worth the effort. (Photo by Devin Mitchell)

Located at La Casa Del Arbol or “The Treehouse” in Baños, Ecuador, this small house was built for the stunning view on the Tungurahua Volcano it offers. But the real attraction is the swing attached to one of the tree's branches. It is far from your average swing, and it is surnamed the "Swing at the End of the World" for a good reason. Located off a giant cliff at over 2,600 meters above sea level and with absolutely no safety features, this swing promises a serious thrill to whoever is brave enough to ride it.
