Falling In Love

How do people really know they are in love? That's a question a lot of people ask sometimes because they don't realize they are in love or the fact that love is right in front of them. Do many people even believe in love at first sight or is that something people just say. People do tend to get love and lust mixed up because of the feelings that be involved. There are some signs that people say what makes you tell that you are in love such as forgetting about your ex, thinking about the other person constantly, caring about the person, not noticing other people, spending a lot of time with the person, and the biggest one which the fact that you think about a future with the person. Those signs are some heavy ones because it seems like love is a drug that you need to go to rehab for if you get too much out of it especially with a bunch of people. At the same time can people really tell or do they just get played thinking that they are in love. Maybe we know, maybe we don't know.
