A very short lesson in Psychology:
When a person laughs too much, even on stupid things, that person is sad deep inside. When a person sleeps a lot, that person is lonely. When a person talks less and if he talks fast, that person is keeping a secret. When a person can’t cry, that person is weak. When a person eats in an abnormal way, that person is in tension. When a person cries on little things, that person is softhearted. When someone asks about you although that someone is busy, he/she really loves you.
