After musing over this substantially, I have taken the liberty of constructing a list of 10 signs which would indicate that a woman is too good for a man (assuming the woman does not possess these same attributes); I base these signs upon foundations of personal insight and knowledge obtained from various ‘enlightening’ conversations with the opposite sex. They are as follows:
1. He is a criminal and has a serious indictable offence under his criminal record
2. He has no direction in life
3. He is a notorious womanizer (and is therefore probably infected with chlamydia, syphilis, genital warts or other STI's)
4. He is a stout believer in archaic patriarchal ideals
5. He possesses disgusting habits
6. He has a twisted sense of morals and ethics
7. He is already married
8. He is a racist
9. He has anger issues and is prone to violence
10. He is too ugly
The following is an example of how to erect a checklist and effectively utilize my advice in a practical sense:

And once again, some music:
"I don't want to talk to you anymore,
I'm afraid of what I might say.
I bite my tongue, every time you come around,
'Cos blood in my mouth beats,
Blood on the ground"
... To end, I will 'high five to better judgment' because 'by saying less today, I will gain more". This is my last bitter post on this subject/event. (Until of course someone stirs my pot again)
