Travel coincidence

About 15 years ago my brother was travelling in Australia. About once a fortnight he would phone my mum to let her know he was ok and then afterwards he would go into an internet cafe to email his 4 sisters. My mum is a dressmaker and had one of her customers in her workroom. They started to talk about their children and mum talked about my brother and the phonecalls. The customer got upset as her daughter was also in Australia but rarely contacted home. Just then the phone rang and it was my brother with his regular call. Mum told him about the customer in her workroom. After the phonecall he went to the internet cafe to contact his sisters and a young girl sat next to him. He said hello and they realised they had the same accents (they had never met before) - it was the customers daughter! He told her that her mum was in his mums house crying and that she should phone her! About 5 years ago, my brother-in-law started to work as a london cabbie. A woman got in his cab and he recognised the accent as being the same as his wifes. He asked her where she was from and she said it was the same town that our family was from. What a coincidence! But then she starts telling him of something that happened in Austalia when she was travelling as a student... Yes she was the same girl that my brother had met in the internet cafe. He told her that she was actually talking about his brother-in-law!
