premise: Because I ' m leaving next week Friday . THEN we talked about Ota - san ( 36-year - old , works at the karaoke place I go after every Japanese lesson ) . They actually bumped into each other at the post office a few days ago . What are the odds of that ... when they had n't met the whole year ? Why were they able to bump into each other at the post office ?
hypothesis: They had known each others day to day cycles and were able to plan to see one another
