What I already know about my topic

I have been wondering what love really is for about five years. I started wondering around the time i had my first real relationship. I guess that is bad to say, but you know i really don't care what kids think of me. What i already know is that is comes in different types. Like you don't love your brother or sister like you do your girlfriend or boyfriend. See my point. Also all humans can love, but the sad part is that some of us decide not to.
