You could write a song about some kind of emotional problem you are having but it would not be a good song in my eyes until it went through a period of sensitivity to a moment of clarity. Without that moment of clarity to contribute to the song it's just complaining.

I like women but you can't always trust them. Some of them are big liars like this one woman I met who had a dog. I asked her her dog's name and then I asked 'Does he bite?' and she said 'No.' And I said 'So how does he eat?' Liar!
