WTF Moment - Medication

I received a text from my wife yesterday while I was at work that read: "I am out of my medication and I don't have any refills."  There's the WTF moment right there.  How in the hell do you not know you are about to run out of a medication you take daily in pill form?  Did you not look in the bottle and notice "Hmm, getting kinda low.  I may want to call in a refill before it's empty."  It would be different if she were mentally challenged and not able to process simple concepts.  But no.  This chick is college educated.  I wonder sometimes why did I get married.
