We have a nice Scottish native speaker at the university who is constantly smiling and she is not pretending it. She is always up for some lovely chat but last time I met her I felt so down that I did not even smile back.
Next time we meet in the morning, I want to say something to let her know that I am not impolite but down.
Here is my idea:
Instead of saying Good morning, I want to say (in a funny way) Good mourning.
How should I put it (given that these two are homophonous) so that she understands what I mean?
I know this is a silly question but spare my life, please.
