When I was a lot younger I would sit and ponder of the idea of glue. It was always a struggle when you accidentally glued something down in the wrong spot. Either you would end with success or failure trying to salvage the sheet. Sometimes you'd ask the teacher for a new sheet when you knew there was no point in trying to redeem the last one. You would either give up or try again. Then when you would ask for a new sheet you were happy because you got a clean slate and tried so hard to make this one; in your eyes perfect. Then you would look back at the old one you tried to salvage and either looked at the beauty in it or you realized that you got exactly what you wanted.
