Let´s see what the stars say...

Sagittarious (the Spinster):

• Optimistic and freedom-loving
• Jovial and good-humored
• Honest and straightforward
• Intellectual and philosophical
• Blindly optimistic and careless
• Irresponsible and superficial
• Tactless and restless

Virgo (Mr Cosby):

• Modest and shy
• Meticulous and reliable
• Practical and diligent
• Intelligent and analytical
• Fussy and a worrier
• Overcritical and harsh
• Perfectionist and conservative

Extremely correct (apart from that Mr Cosby hardly is anywhere close to being either modest or shy!). And as you might have guessed, not the perfect match, the stars say!

It will take work, but it can be done. The independent character of each, reserved Virgo and exuberant Sagittarius, may thwart all understanding. Confident Sagittarius strides ahead, optimistic and ambitious, whereas anxious Virgo pulls back, careful to avoid danger as much as possible. Sometimes the couple may function as a complementary unit. Thus, Virgoan tact may compensate for Sagittarian frankness, and Sagittarian enthusiasm may banish Virgoan anguish. But basic differences are difficult to overcome, and this couple often succeeds only by an implacable effort of will.

But who cares about stars anyway? Bah!
