The song "How Do I Know?" by Thomas Headon is about a man who is unsure about his feelings for a girl and whether he wants to fall in love with her or if it's just a fleeting moment. He meets her on a second date and is immediately taken with her, saying he loves her after only half a glass of wine. They end up spending the night together in a hotel room, which he had booked thinking he would be alone. Throughout the song, he questions how he can know whether he truly loves her or if it's just a momentary feeling. He wonders if she's the one who would hold his hand when he's dying or if he would talk about her to his family. He ponders if their relationship would work when they're sober in the morning. Despite his uncertainty, the man wants to treat the girl right and feels that she's more special than his previous girlfriends. He even considers getting a ring to show his commitment to her. However, he's still unsure if his feelings are genuine or just a product of the moment. Overall, "How Do I Know?" is a song about the uncertainty and confusion that can come with falling in love. It explores the hesitations and doubts that can plague a person when they're trying to navigate their emotions and figure out if they're ready for a committed relationship.
