Placing the needs of another ahead of yours, and expecting nothing in return but their happiness. Supporting someone and being there for them regardless of the outcome of their endeavors. Never feeling like anything you do for them is a sacrifice, even if on paper it is.
When I love someone, I just always want to touch them or feel their hands on me. I always want to look at their face, i always want to hear their voice. I always want to tell them in some unique way everyday how they make me feel. When I love someone I feel lucky and I always want them to know it.
