I was reading this article and a lot of it made sense:http://ezinearticles.com/?Does-Love-Exist?&id=2801470
We only want to be around people who make us feel good. If a person is boring and not fun then we don't really want to be around that person anymore. Maybe love is just a selfish impulse to make somebody be around us more because they make you feel good. This can get pretty depressing if you think about it really hard.
What makes you memorable?
