Reason 2: When you know what love means to you.
Words are so powerful that when you share them, they become an imprint of your life into the heart of another. Be careful with words as their echo change the giver and the receiver forever.
Make sure that whenever you share an "I Love You", you fully understand what it means to you so that you can always clarify its meaning in the most accurate way.
BUT ON THE BRIGHT SIDE, even the concept in itself remains unfathomable.
like love you.
p/s: I Love You.
