Sorry, I prefer to imagine it turns red because it is embarrassed that it is going to bed - sometimes with the moon, but mostly she gets away to come and smile on us.
Hmm, in Greek the moon is male to feggari, whereas in English she is a pale maiden. To make it more confusing, she also has the "old man in the moon" - apo tois skies, vouna kai alla, fenetai san prosopo.
nai exeis dikio... fenetai san prosopo de to eixa proseksei...
an eisai kala mia xara kai i fantasia!!!
