I will try to explain the song in the way i think which (by the way) might all be wrong:
The song starts with a lazy woman may be a housewife on a Wednesday...she has inner feeling of fear though that she said that she was ok and nothing to fear of...
"the Persian we call Cajun" means her Persian cat whose name is Cajun. and if he sleeps so well so nothing to fear of...all the thoughts about what she was going to do must be all crap
the fact that sh she may be about to go out and she was going out to run some errands and there is some thing deep within which was telling her that she might see something to prove all her doubts that day,,,,
she knew that he husband was betraying her with a mistress thought she didn't want to believe herself ( she see all the evidences... hang up phone calls... mysterious knocks on the door.. her husband daily tours out) she trying to convince herself that if he was betraying her she would certainly knew this and she cant believe the fact that a mistress might be another old woman... not a usual Thumbalina girl but a size 10 mistress..
i Think she went out and decided to follow him and then she saw him with her and she couldnt cry and ( plucked up) her courage and kept silent cos she can't imagine knocking down the house of marriage which she was trying to build for many years.. and she said( After all the eagle has to land) and he would return again to her
but it seems that both of them kept secrets from others , he with his mistress and love affair and she with her( unpleasant sex without orgasm) she always had ( i guess that what she meant by PRINCE song When the Doves Cry cos the woman there wasn't satisfied and may be that was her own secret !!!)
