Playing DotA is like having a child:
Sometimes you're going to get angry by some of his malcontents or your friends who are usually nasty, but you have to put up with it, because it's your responsibility as a parent.
However, most of the time you will be happy to see that he is evolving and becoming a good guy and, as he grows, you feel more and more proud to be part of it.
It may be that at one time or another, you take time away, due to the occasions of life, work or lack of time, but you always see your boy again, after all you love him and always will have him in your life and when you find him, will miss so much, that will be UNSTOPPABLE.
Playing DOTA is that.
