In life, you choose who becomes your friend. You determine the type of person you want around you, be it a good or a bad friend. A friend you'd hope will remain by your side through the thick and thin. But try as you might, you always feel that friends can only help you to a certain limit before you know you're on your own.
Families, you don't choose them. They are God's gift to you. Curse your luck for getting a nasty sister or a big fat brother, they are part of you and that is final. It's not exchangeable.
But ironically you can always be sure that families will always be there for you, when no one else does.
As one saying goes, the only rock I know that remains steady, and the only institution that I know works, is FAMILY.
Love your family. Pray for their well-being in this world and in the hereafter. Don't break their hearts for you're only gonna break yours.
