Love means giving your heart to someone that you can trust. Usually, love makes people do crazy things.
One kind of love is romantic love, one between two people. Romance is also closely tied to sexual attraction, and is sometimes confused by the two. Two people usually try to test the waters first, trying to find out if the other likes the other, courting them by giving them flowers and chocolate. If the two find out that the attraction is mutual, the pair tries to pursue their relationship further. As time passes, the duo will either fall harder for each other, or slowly start to fall apart. If the two falls in love with each other, then they will get married and live a happy life. Sadly, human cycle only lasts for such a short time that they are forced to be apart by death. As a result, the person that has been left behind will feel empty and broken. Sometimes, people that truly love their other half commit suicide after, just so that they could be together.
Another kind of love is maternal love, one that a parent/parents harbor for their child/children. Parents sacrifice a lot for their children, working jobs when they could be doing nothing or just relaxing, paying for their children's education when they could be saving up their money for a trip around the world, to just plainly having to take care of them from infancy to teenagehood, or sometimes in early adulthood. Children should try to appreciate their parents more, since they are the ones providing everything that the child needs.
Hope that would be helpful.^^
