In these dark days of 2017, it takes a lot to warm the cockles of our cold, cold hearts.

But a seven-year-old girl from Birmingham has managed to do just that, after receiving the best reaction from her friends as she proudly showed them her new prosthetic leg.

Anu, from Birmingham, was captured on camera as she bounded into her school’s playground to debut the new, hot pink sports blade, which was greeted with amazement by her friends.

Gathering around the little girl and shouting her name, the group looked on as she flexed the blade, with one asking, "is that your new pink leg?" while another simply exclaimed, “wow!”

Two of the friends enveloped Anu in a hug before the delighted group set off on a sprint around the playground, which ended with Anu holding hands with a friend as they marched around in the sunshine.

The heartwarming video, which was shared on Twitter by BBC Midlands (below), has quickly gone viral, amassing 27,000 retweets and 44,000 favourites (at the time of writing).
