it is hard to maintain a relationship - just like flying kite.

you have to pull at the right time, let go at the right time..

it is not easy. you will be afraid of string snapping off, hence u keep letting go and let it fly far and high. by that time, you are unable to pull it back. it will fly real far.
on the other hand, if you pull too much..although it is near you, if the string snap off, it will be gone too.

difficult isn't it?
