Emily Tingle

The pleasant, if sometimes disarming, sensation that two people who know Emily but don't know each other feel when their eyes meet in a public place.

Although they had never met, A and B felt a palpable surge of electricity pass between them when their eyes met as they tried to attract the bartender's attention. It was only months later they found out they both knew Emily and that it was the Emily Tingle that had brought them together.
