don't be a stranger

English

(imperative) Remain in communication with me.
- 2010, Jennifer Egan, “X's and O's”, in A Visit from the Goon Squad:
  ‘Don't be a stranger, Scotty,’ Bennie said. He sounded bewildered, as if he'd forgotten how I had come to be there; as if he'd invited me himself and I were leaving prematurely.
