Mixed Feelings

When people meet someone new, one individual (he and/or she) is either happy, sad, angry, or really surprised. Is it just a bunch of different attitudes or just mood swings? It seems that every human being is way too emotional, but they're not, which is really weird. Maybe everybody should know what these mid-life/mixed feelings are. Every time I see a lot of mixed-up feelings from one one too many people, it's like a possible chain reaction. And when everybody watches the local news, they're either mad, sad, or glad like winning a sporting event, auto accidents, or whatever. Even when two lovers get together, break up, or rekindle their relationships, they still have mixed feelings for each other. And what are these feelings doing to all of us human beings? They're taking us on a roller coaster ride. But if this keeps up, who knows what might really happen next?
