Maturity begins to grow when you can sense your concern for others outweighing your concern for yourself.
- John McNaughton
I do believe that when you start to stop nagging about why he's late, or having tantrums of why he can't call you every mintue, or if you stop pouting when he can't drive you all the way to your far far away home on weekends and when you rather he sleeps early than have a night out together. You stepped into that border line. Suddenly, your love has evolved in to a deeper and more mature level.
