When someone laughs too much, even on stupid things, Be sure that person is sad deep inside.
When someone sleeps a lot, Be sure that person is lonely.
When someone doesn't talk much, and if he talks, he talks fast, Be sure the person keeps secrets.
When someone can't cry, Be sure that person is weak.
When someone eats in an abnormal way, Be sure that person is always in tension
And finally... When someone asks about you, although that person may be busy, Be sure that someone loves you :)
