I didn't mean kicking them out if they were busy with real life, sorry if it sounded that way. However, I do believe a person should mention it on the OOC if they will be gone for sometime. That way, the GM can usher their character along or place them somewhere where they won't hinder the story. If they're going to be busy and say so, then they shouldn't be booted out of the RP, but players who are constantly inconsistent for no reason at all, those who miss several posting cycles with no warning, and those who simply vanish off the face of RPG, they're the ones who need to go.
