Obsession with Odds

Today, once again, my fiance showed her somewhat odd obsession with odds. I don't mean the types of odds like coincidences or betting for or against horses at a race track. I simply mean she is obsessed with odd numbers. When she puts things in the microwave, odd number always for the last digit she presses. A couple of examples "4:25" or "0:95". This girl is math crazed and her favorite style of number is the odd number, just because it is that single digit more that makes it unique and imbalanced.
