erik de vries , 24 , and josephine egberts , 22 , were separated back in 1999 after their father took erik and his mother stayed with josephine in their native netherlands , reports datingsitekiezen .
despite erik and maarten 's best efforts to later track down their sister , it was only after erik moved back to the netherlands , joined tinder and swiped ` right ' on josephine 's profile that they were reunited - but the penny did n't drop straight away .
tinder - dating app which boasts 21 million matches each day - only allows two people to message each other if both parties express an interest .
