It’s a concept. I don’t think a lot of people think about the fact that love and hate can exist at the same time in our heart. Happy and sad can exist at the same time. That’s where the term bittersweet comes from. We have opposite emotions or how we call them conflicting feelings. These can happen at the same time. And it’s completely normal. It’s natural, but people don’t know how to interpret that. When it happens, they feel crazy, because it’s like, how can I love this person, but hate them and don’t want them in my life. How can I be happy that my son is going off to college, but then broken and sad. The minute the door closes behind him, conflicting feelings exist all the time.
