Social bubble (or interpersonal bubble) describes the situation in which people seem to have a wide range of social connections, but when it comes to real friendship, few remain in the circle. Following the wave of financial bubble and real estate bubble, social bubble is showing up among office workers in recent years.
Your office drawer is filled with name cards whose owners might be total strangers to you. There are many contacts in your instant messenger that you may never start a conversation with or whose name has slipped from your memory. You may have many “friends” in your cell phone contact list, but there is no one you can talk to when you are upset.
