ya….yesterday is the painkiller of today. All memories are sweet, no matter happiness or sadness. Recalling the past is always joyful.

Yesterday is the cause of today. What you did in the past can directly or indirectly affect the current or future conditions. They may be good or bad. Yesterday can be the killer of today in the result of poorly-prepared yesterday.

However, I still think that yesterday is the panadol of today, though now I’m suffering from the poorly-prepared revision before.
