Actually thats just how emotions work - they are "catchy" between people like colds. When we look at other people, our brains are working so fast, we are catching all these little signals another person is giving off, even without saying anything. We are often not even aware that we received these signals. We might just have a feeling somebody is angry for example.

Saying something is gods plan is like saying everything is made of atoms - it doesnt really help you understand or answer your question, or explain things - its like giving the same explanation for everything; you want MORE, deeper information.
