revamping friends list

I went through my friends list againtoday and removed some that never message me whatsoever.  i don't like doing this but, I see no need of 40 plus "friends" and only hearing from a minute few.  I have a few others that are questionable and if I don't hear anything from them in the near future, I will delete them as well. I get tired sending message after message, hug after hug and, never even getting an acknowldgment of either so, I look at it this way, if they don't want to correspond with me, then why be on my friends list.  Friends don't do friends this way.
