Lyric discussion by JonnyTheMohawk 

Cover art for That'll Be The Day lyrics by Streetlight Manifesto

"gone! everybody's crying now you're gone and everybody's missing you: from apathy to sympathy this new found love is new to me and i can hear you laughing in your grave everyone's forgiven now we're saved every single sin absolved what's the point denying when we all know we are lying to ourselves (and you can't keep that smile off your face)"

I feel this song may be about god/jesus and how thomas feels like its a big lie. Just my thoughts but it makes sense.
