First kiss turns into panic One touch from you, I'm frantic I'm terrified that I might fall Past love did me some damage Past boy, way too volcanic So hard to let down all my walls Rules, I'm breakin' my rules I'll lose 'em for you So here's a little piece of my heart It's not a lot, but it's a start I'm sorry if I make it hard Even when I'm in your arms So here's a little piece of my heart I'm scared of lettin' down my guard I'm scared to give it all at once But I can give it part by part So here's a little piece of my heart So free, so energetic Lightning strike down from heaven You got me fallin' in the dark Rules, I'm breakin' my rules I'll lose 'em for you So here's a little piece of my heart It's not a lot, but it's a start I'm sorry if I make it hard Even when I'm in your arms So here's a little piece of my heart I'm scared of lettin' down my guard I'm scared to give it all at once But I can give it part by part So here's a little piece of my heart I'm fightin' back feelings For a million reasons But, little by little, I'm healin' I'm fightin' back feelings For a million reasons But, little by little, you heal me So here's a little piece of my heart It's not a lot, but it's a start I'm sorry if I make it hard Even when I'm in your arms So here's a little piece of my heart I'm scared of lettin' down my guard I'm scared to give it all at once But I can give it part by part So here's a little piece of my heart Here's a little piece of my heart Here's a little piece of my heart
