Marriage, really! I have seen some people that don't comply with this idea as a necessity to life. That doesn't make it right or seems like the best of ideas though.

Life is a puzzle, I can go with that idea and it's only left for one to pick up the pieces and fit together to paint the sort of picture that would be appealing to you and that depends solely on your fittings of the pieces.

One thing I've come to understand and accept about life is, it ain't fair and all the forces to it is against you. Even as a religious believer, there is a part called 'Temptation or a testing'. Why should you be tested in the first place...
As a human capable of thinking and solving problems, you ought to do that. Think and solve your problems as they come and never 3xpecting any accolade  or help from anyone. Life gets a lot easier that way.
