In this July 15, 2015 photo, Nepalese amputee victims Khendo Tamang, left, and Nirmala Pariyar, both 8, share a single pair of shoes at the Bir Trauma Center in Kathmandu, Nepal. After suffering serious leg wounds in Nepal's massive 2015 earthquake that killed and injured thousands, both girls were brought to the Bir Trauma Center in Kathmandu, to receive single leg amputations. Following their surgeries, Nirmala's relentless cheerfulness drew a still very depressed Khendo close and both found an inseparable friendship which has helped their emotional wounds heal.

This is a “swami” - Valeria Lukyanova (born August 23, 1985), from Odessa, Ukraine. Her other names: Naamah (Нахема; Na'amah (Hebrew: נעמה‎) – is a demonic legendary creature, the mother of divination), Amatue, Nagval and Goddess (бАгиня). She is fond of esoteric, believes that 2012 will be the end of the world, and waits for the planet Nibiru (I'm not kidding). This girl had amused the Russian-language Internet (because the Russians are cynical and heartless people). IMHO she is very beautiful (technical characteristics – Chest: 88cm (34,64 in; may be longer already); Waist: 47cm (18,5 in; may be lesser already) and Hips: 88cm (34,64 in)). Enjoy.

“Are you here for the Winery Tour?” This is a Western Grey Kangaroo caught lounging in the wineries of the Adelaide Hills in South Australia. This past Autumn has been a spectacular time for wildlife viewing and I got lucky to spot this guy while mountain biking in the hills. Such a funny stance it just begs the question... Have you been drinking? ...and or... Are you here for the Winery Tour? Such a spontaneous moment I figured it would be perfect for an entry. I hope you like it! Cheers. Photo location: Adelaide Hills, South Australia, Australia. (Photo and caption by Greg Snell/National Geographic Photo Contest)
