Head meet pillow; pillow meet Zzzz....

Have you ever been so tired, worn out and beaten down by your crazy-hectic day that as soon as you lie down on your comfy bed and rest you head on your fluffy pillow you're out like a light? I miss those nights... I miss being carefree. I miss not having to think about my problems. I miss not having problems. I miss having the luxury of being irresponsible. I miss being tired because I just had a fun-filled day and not an avalanche of mundane tasks that took up my whole day. And most of all I miss being oblivious to life......... What do you miss?
( Hmm funny....For some reason I get those kinds of peaceful nights the night before a Calculus exam...)
