"Venir" followed with a gerund, often refers to something that has been occurring for a long time and is still continuing. It sometimes conveys frustration that the action isn't complete. As in the first two examples below, it is often used to indicate how long something has been occurring. - En los últimos años, se viene hablando de liderazgo. (In recent years, much has been spoken about leadership.) - Hace seis meses que viene probando suerte como modelo en París. (For the past six months she has been trying her luck as a model in Paris.) - Vienen diciéndome que no soy normal. (They have been telling me that I'm not normal.)
