Shaker Aamer, Britain's last captive at Guantanamo Bay, has been giving a series of news interviews this week following his release at the end of October.
After more than 14 years in captivity without ever being charged, Aamer has returned to his family in the UK.
As well as telling extremists to "get the hell out" of Britain and likening Guantanamo to the prison of Azkaban from the Harry Potter novels, Aamer has explained the very simple joys of being a free man once again.
An excerpt from an interview with the Mail on Sunday has particularly caught the public's attention:
A few days ago, I was with my daughter, using our Oyster cards to go through the gates on the Tube, and there was this guy in a wheelchair. He asked me for help, to push him to the bus station. He was a clean-shaven white guy and I’m an Arab with a beard. I said, 'Of course I will help you, and I’m so happy you asked me.'
It was a little bit uphill and I pushed him all the way and I was talking to him. Fourteen years I’ve been controlled, 14 years I haven’t talked to a normal human being, and here is somebody who will talk to me, who isn’t scared. I was so happy because I felt like, yes, this is it, I’m back.
The quote, along with a picture of Aamer, was shared on the Facebook page of Reprieve, a activist group which has campaigned for the release of prisoners from Guantanamo - it has since been shared more than 4,000 times.
