Yated Shidduch Forum 6/21/19: How Should I Handle An Unexpected Encounter With My Ex or His/Her Parents?

Question:
What’s the protocol for when a boy bumps into the parents of a girl (or the girl herself) after having been on a few dates and the shidduch ended respectfully and/or mutually:
A) Ignore.
B) Turn red, avoid eye contact, and reverse course.
C) Give a quick nod and move along.
D) None of the above.
I’ve experienced this awkward situation time and again and would appreciate your guidance.
