When did we forget All the crazy things that made us feel so part of it? Our youth, so confident We played our heartstrings Not caring if it ends Try to learn to let go of all those things that tie you down Get rid of it, the voice inside that tells me that I'm scared, yeah, scared as shit But I wanna let go of it now So someone tell me Why so serious? Why are we so serious? Oh, why so serious? When did we get like this? I still remember we weren't grown up like this Oh, oh I don't seem to get all the things that are happening And I can't make sense of everything that's inside my head But I keep on thinking, there's gotta be something said Oh, seems we've lost it That spark inside that tells us it's all nonsense Stop being so cautious With every mistake there comes a lesson learned So someone tell me Why so serious? (Serious) Why are we so serious? Oh, why so serious? (Serious) When did we get like this? I still remember we weren't grown up like this Oh, oh Why so serious? (Serious) Why are we so serious? Oh, why so serious? (Serious) Can someone tell me Did we forget about Living with no regrets? Oh, oh I wanna live in the now I'm not gonna live in the past Don't wanna care about what-ifs 'Cause what if those things don't last? And I wanna live with no regrets I wanna live in the now I'm not gonna live in the past Don't wanna care about what-ifs 'Cause what if those things don't last? And I wanna live with no regrets So someone tell me Why so serious? Why so serious? (Serious) Why are we so serious? Oh, why so serious? (Serious) When did we get like this? I still remember we weren't grown up like this Ooh, oh Why so serious? (Serious) Why are we so serious? Oh, why so serious? (Serious) Can someone tell me Did we forget about Living with no regrets?
