If you really donot like them, obviously you have to get rid of them. You retain them, (even if they are not helpful to you financially or in kind)if they are good. You should not get rid of them just because you are selfish.
1st either they are frnd or no frnd with them.2nd u dont wanna meet them again ,tell that on face...100 lies are no better than a truth.3rd wanna get rid of them when they still hang around...frend u always have a option to walk away.
