When two people of the same name meet each other in school, workplace, etc., how do they address each other? In our language, we sometimes use a term and it sounds like the following:
1. James is addressing his classmate with the same name.
Hey, namesake, have you seen my (public) post on [social media]?
2. Jane is referring to Peter's coworker with the same name.
- I forgot to send the fax to the client before I left. I cannot find the document now.
- Don't worry. It was sent by your namesake yesterday before shredding the document (with sensitive details).
But I don't think native speakers use the word namesake that way. What do you normally expect to hear in that situation?
