They include you in their life
They don’t hide things from you. A loyal person makes you a part of their journey in life. Whether it be the dreams they want to achieve or goals they have in mind, they want to share all of their moments with you because loyalty is another way of showing love to people and they don’t shy away or waste the opportunity of including you in their life. They are committed to you and that is why they include you in every aspect of their life. You matter to them!
