For a time you can be alone and doing fine and never give a thought to living any other way and then you meet someone and suddenly you become lonely. It stabs at you, almost like a physical pain, and you feel both deprived and angry, deprived because you wish to be with that person, and angry because their absence brings you misery. It's a strange feeling, akin to desperation, a feeling that makes you wait by the phone even though you know that the call is an hour away.
