How do I tell some people that I do not want to accept their friend invitation on Facebook?

There is a difference between friends, relatives, colleagues or even aquaintances.

No point clicking on the 'Ignore' button because they will add you again.
*sigh*

I lead many lives you know, which probably I am not willing to share.
Its like I wear different masks in different theatres.
But I'd like people to think that I only have one.

As such, I do a refresh of my friend's list every 3 months.
Scroll the whole list and see which one I feel like deleting.

To date, I have about 150 friends.
Sometimes, I wonder who the heck they are.
While they feel a need to build up a list and be a serial friend collector, I do not.

Yes, another refresh cycle coming up soon.
