Confused by this

Walking down the same concrete bridge Wondering how I found myself here Last thing I knew I was driving through This whole new world, a whole new world Sitting on the same old bus Terrified that I'll miss my stop But I never do Sometimes I wish I would I never thought that I would get so lost Coming home, coming home And I never dreamed for time to pass me by Please pass me by Walking like a zombie off to class Please don't bother me listening to my same old tunes I'm trying to take this all in But I'm locked out of the house And my room's a mess I never thought that I would get so lost Coming home, coming home And I never dreamed for time to pass me by Please pass me by And I'm confused by this
