Her PMS again??!!

Believe many of you guys have heard this before.

 

Out of nowhere, she brings up something that happened a year back (esp. something involving a seemingly third party affairs). Next, seems to obsess about “that issue” better left alone, then get an idea in her head and fixate on it, even if you have already explained why it’s no big deal.

 

So, why do u think most girls repeatedly react this way?
