"I Love you": three words that take the relationship between two people to an altogether different level. When you say that you love someone, you are bound to have feelings for the other person. These words have a special meaning and are said to someone special. That is the essence of these words. You say "I love you" to someone for whom you feel truly, madly and deeply.
Being in a relationship is a special feeling and hearing these words from your beloved and reciprocating back in kind is what a relationship is all about. Say these words to someone who respects your love and also reciprocates in a similar way. One-sided love has no meaning and is a sheer waste of time and energy. Refrain from running after someone who is not interested in you. Better spend time on things which deserve your attention and with people who like being with you.
