There was this boy back when I was fourteen Not my type but I knew he took my shit seriously enough Couldn't help it but with him, I always felt so cool He cooked me dinner and surprised me with trips Went abroad and then came back with his suitcase full of gifts But it was too much too soon so I freaked out and then I called it off I didn't know shit about heartbreak I didn't know shit about love, and I ran around breaking hearts everywhere I went Didn't know how bad it hurt to mend Yeah, I was selfish Arrogant but couldn't help it If I knew what I know now, I would've never let it go that far But I didn't know shit at all, all I didn't know shit at all, all When I was sixteen, I met a girl at home I thought it was forever for a minute or so We'd be at the beach until our parents came and picked us up And then I think that faded out like grown-ups in a film I slowly stopped texting her, I guess I lost a feeling, oh I know I should've told the truth instead of drifting off We didn't know shit about heartbreak We didn't know shit about love, and We ran around breaking hearts everywhere we went Didn't know how bad it hurt to mend Yeah, we were selfish Arrogant but couldn't help it If I knew what I know now, I would've never let it go that far But I didn't know shit at all, all I didn't know shit at all, all Sorry for the ways we led you on for days If we would meet today, it wouldn't be the same We didn't know shit 'cause we were only kids, so sorry Didn't know shit about heartbreak We didn't know shit about love, and We ran around breaking hearts everywhere we went Didn't know how bad it hurt to mend Yeah, we were selfish Arrogant but couldn't help it If I knew what I know now, I would've never let it go that far But I didn't know shit at all, all I didn't know shit at all, all Didn't know shit at all, all (Sorry for the ways we led you on for days) (If we would meet today, it wouldn't be the same) We didn't know shit at all, all (We didn't know shit 'cause we were only kids, so sorry) Didn't know shit at all
