A mystery man gave a young mum a kind note of encouragement and a £5 tip for being "polite" and teaching her child "good manners".

As the passenger was getting off the train, he passed her a handwritten note that described the young mother as a "credit to her generation."

Sammie Welch, 23, was traveling with her three-year-old son on a busy First Great Western train in England last week when she pulled the child out of a seat and placed the boy on her lap so another passenger could sit down.

She explained: ‘As he walked by he tapped me on the shoulder and said, "I think you've dropped this out of your bag," handed me the note and got off.

She launched a social media campaign to find the man so she could thank him for his kindness. Now the two have been reunited to talk about what happened.
