Having someone in your world whom you can rely to is great
Having someone who just want a smile on your face is great
Having someone who maintains contact with you when you don't initiate is great,
Having someone who can predict your mood the way you reply is great,
Having someone who waits for you is great,
Having someone who reminds you of how good life is great,
So if you are having that someone in your life, let them know it.
How their actions are making your life great, even if they are close to you or distant. Let them know how great they are for once.
