Sarah and James met the traditional way--James sent a message on Tinder and Sarah never responded. A few months later, James figured enough time had passed that it wasn't super creepy to send a message on OkCupid as well. They promised each other that they wouldn't take things too seriously, and never wanted to get to a point where they couldn't break things off easily if they got messy. So, a half decade later, they're getting married.
