Earlier quoted context omitted.
The average person has about 150 people they care about. 100 friends is par for the course imo
150? What about 5-10? I don't believe you can have 150 people you really care for.
Conversely, there are plenty of friends whom I know personally, but did not connect via Facebook (we use IM for that). This may probably be counted towards the close friends I really cared for; only few (no more than 10) people fits this criteria of mine.
