Grammatical mood differs from the mood expressing emotions

How enjoyable is it going back to work on a Monday? Chances are that you are not very enthusiastic about Mondays, but there is nothing you can do about it except, perhaps, be moody. So commonplace is the feeling that the mood has been captured in the idiom; ‘Monday morning blues’. This was coined to express the lethargy that informs Mondays.

The ‘blue’ mood, however, does not restrict itself to Mondays, hence the other expression ‘Morning blues’. The latter mood can occur on any day for varied reasons unlike the ‘Monday only’ morning blues which, basically, are about reluctance to exert oneself after a relaxed weekend during which not much is expected from an individual. Because of routine, workdays tend to be drab. Nobody looks forward to being bored, but it is that monotony that drives life and makes us realise our basic needs.
