Bow without arrow

Relationship is like a bow and arrow.
If you pull the strings more there's chances of breaking the bow, if you pull less than there is chances of travelling less distance by the bow, so pull it less without arrow and bend more because neither the bow gets broken nor there remains a doubt of flying your arrow less distance.
Bow and arrow got a good relationship because how much you pull the strings same the bow bends.
But this relationship last for sometimes and when travel less than it's a puppy love. But to use bow or play archery for lifetime with a same bow and arrow pull less bend more. When a girl pulls bend more the boy and when boy uses energy to pull less girl you bend more, although girls are perfectionists to pull out more
