well, my opinion is that absence does really makes the heart
grow fonder 
sometimes seeing each other too often is not a good thing. u end up
squabbling more often.
being away from each other increases the fresh feel of a
relationship. u end up having more things to share to each other
cos you haven been updated for a while..
but of cos u cant be away for too long a period of time..if its too
long a period, you might as well not have each other...right?
