Character mistake: When Carrie tells her friends she accidentally left her passport behind while buying shoes, she mentions she left it behind because she saw Aidan... but in reality, she left her passport behind because of the "call to prayer" sound she heard on the loudspeaker and then walked away towards the sound - THEN saw Aidan. Carrie's own story was incorrect to her friends (as Aidan initially had nothing to do with it).
Suggested correction: Even by the mistake's own entry it still sounds like seeing Aidan is why she forgot her passport. Just because she went to investigate the sound didn't mean she forgot her passport, meaning she could still have had the intention of going back for it. When she saw Aidan, going back for the passport slipped her mind.
