It's strange how they can change our mood by just some letters!

It's strange how they can change our mood by just some letters! How can they make us feel like we're flying as butterflies or make us feel that we're alone & no one is around us by only an eye contact!How can they make us feel hot and our hearts beat as if we're running in a marathon by only a tough of hands ! How they're controlling our life easily ? Actually I don't know but maybe we're weak otherwise love must make us​ strong ! I don't know it's complicated 😑
