If you truly love someone, then they never leave your heart, only your side.
When someone is truly happy with a person they are involved with, the mere thought of their lover will give them a smile. It is such a great feeling to know that you are with someone who just lights up your world with one thought, and it is also important to note that having someone in your life as such is really a blessing that not everyone is able to say they have. When you have someone that makes you smile when you think of them, be sure to work hard in your relationship with them so that they will smile when they think of you as well.
Remember that if someone really loves you they will only want you to be and act at all times as yourself. Also one must note to never take things for granted. Handle every day and every time with them, as it could be your last, because you never know if it might be or not. Most of all, walk in love in everything that you do, doing so will make your life and your relationships flow with ease and happiness.
