the evolution of 'tatah!'

you know the way it's the little things that give you direction on where things are going? a good example would be the evolution of goodbyes to indicate where things are upto...

• 'well that was fun... maybe we'll catch up again?'
• 'we should hang around again some day...'
  
• 'see you...'
• 'see you soon...'
• 'i'll see you soon, ok?'
• 'i'm going fishing for the weekend, so i'll see you on monday?'
