It's not a big deal if you do it for just someone in your life. But it'll last forever hurt in your mind, if you do it for someone who has an important meaning and role in your life. Someone whom you would always expect to make you smile, specially on a surprise-things-situation, even if it wasn't a red blooming rose, although it's just a piece a paper, written... "happy birthday", or just a simple "hi!".
anyway.. i'm still questioning the power of roses..
