Life in general

Is it just me that notices that every single day starts or ends in almost the same way. You either wake up in a good mood and your day is absolutely great and nothing could stop you. Or you wake up on the hypothetical wrong side of the bed and your day is all toast and nothng seems to go right for you. But then there are those occasional days were you wake up and you are in a bad mood but something comes along and you are all of the sudden in a fabulous mood?
