Things below happened since months ago:
- went to same theater for same show but didn’t see each other. Didn’t meet.
- went to same place, 1 went into to left, at the same time, another walked out from anther left. 1 saw another when left closed. Didn’t meet
- took leave in a same afternoon, made appointment in a same place and at the same time but difference doctors. Didn’t meet.
- in the restaurant, 1 sat inside and another 1 sat outside. Didn’t meet.
- …….
- …….

So drama. 两条平行线真的有交会的一天吗？
