What is me constantly deleting friends on my myspace/facebook profile suggesting?

in each day to spend with friends. I don't delete any. I always hope to keep in contact with them sometime in the future. It is ok if I don't hear from them for awhile. They are wonderful decent people. I value all of them. I think I have 2 people who did not know me well before they asked me to be their friends, but it is ok...people who are different than me add spice to life.
