We had a sushi lunch at the Metreon . After that we parted ways so Josh could meet up with his sister . I would have loved to come but she was in the opposite direction to where I 'd agreed to meet my colleagues in a couple hours , so he went alone and met up with us later . I wandered around for a while and then went to the SF office to gather my colleagues .

Question: What is the author 's relationship with Josh ?
The author is Josh 's friend .
