Ed Sheeran said-

"'The A Team' came from an experience I had when I did a gig at a homeless shelter," says Sheeran of the song. "I was 18 at the time and kind of quite naïve. So, I was a bit taken aback by some of the stories that I heard. I got home that night and I just wrote a lot of the lyrics. I wanted to write it so it sounded kind of upbeat, so you wouldn't really know what it's about, because it's quite a dark subject."

My heart goes out to people who deal with this.
