Green Day - No One Knows lyrics

Why should my fun have to end? For me it's only the beginning I see my friends begin to age A short countdown to their end Call me irresponsible, call me habitual But when you think of me Do you fill your head with schemes? Better think again 'cause no one knows I don't want to cause no harm But sometimes my actions hurt Is there something I should find To make plans for forever? Call me irresponsible, call me habitual But when you think of me Do you fill your head with schemes? Better think again 'cause no one knows Call me irresponsible, call me habitual But when you think of me Do you fill your head with schemes? Better think again 'cause no one knows Does it seem like all your memories fade? You soak up knowledge to fill the space And still my answer remains I don't know
