A warm shelter, a cozy place and a safe place all of the three can be defined in one word i.e. Parents.
A sweet, loving, caring and supportive relationship between them is an undescribed bond. Parents are the safe house of a child whenever he is in the need of anything, in fear of anything, the first one he or she will look upon to are parents they provide you guidance and care for you till their last breathe.
It's a relationship of love, a relationship where there is understanding, care, support, love, happiness, fights, lessons and what not.

This relationship is a lot bigger than universe itself. Take away child's favorite toy he will cry, take away his parents he would die. A thought which describes the relation of parents with their child. From day one till the last day, till their last breathe they are always with us, bucking us up if we fall, helping us if we are in grave situation. Each and everything from our happiness to our sorrow everything is faced together.
Thus parents are the lifelines, the God and supporting pillar in child's life.

Love your parents never let them go no matter what happens. There will be ups and downs but never let go on them.
