In the quote from James Patterson's book Angel, the narrator finds it odd that two characters are friends. This implies that their personalities or backgrounds might be unusual or different from the norm, making their friendship seem strange to the narrator. Despite this, there is a suggestion that people with unique or 'freak' qualities are naturally drawn to each other, creating unlikely but genuine connections.

The quote explores the idea that shared differences or peculiar traits can be a bonding factor. It hints at the notion that outsiders or unconventional individuals often find solace and friendship among themselves, forming bonds that might seem odd or unexpected to others but are meaningful for those involved.
