A location and activity aware content delivery system stores a plurality of instances of media content relating to known locations, and each of the instances of media content that are not generated by a mobile device user at the time the user is engaged in an activity proximate to the known locations. The system detects a current mobile device user location, emotional response and activity, selects an appropriate stored instance of media content and delivers the selected media content to a friendly user if the emotional response is positive, and does not deliver the selected media content if the emotional response is negative.
