Some people really have a hard time expressing their feelings and words like “I love you”. They were never told they were loved all their childhood and they feel unloved themselves. They were told to keep their feelings to themselves. There are all kinds of people in the world. Some are so inept with their feelings. We have to open our minds and our hearts that these situations exists and be understanding.
Knowledge is power; speak out and express to make people know how you feel. Don’t expect people are sensitive enough to observe you.
