Chance, or not?

"Though Joshua saw no one- he once passed me right by..." 

(Blorts, 144)

This commentary about Joshua is important mainly because it gives the ending more meaning. Up until this point, we are lead to believe that the narrator and Joshua simply met by chance. 

When they first met, Joshua claimed that he and the narrator had seen each other at the beach- or rather that Joshua had seen the narrator, while he had stared at Joshua's "blorts". However, the commentary from above suggests that this could not be true, since "Joshua saw no one". This then brings into question whether Joshua really saw the narrator or not. 

However, this is essentially answered when Joshua admits at the end that they did not meet, but rather that Joshua purposefully "picked up" the narrator. But in that case, did Joshua really have nowhere else to go when he asked the narrator to move into his apartment, or was that also a purposeful move in order to get closer to the narrator? We might be the last to know.
