Seasonal affect disorder

I've noticed that I, as well as other male friends, get these little, reoccurring crushes on a few select girls. When it sets in, I'm forced to go through the same process of reminding myself why I quickly got over it in the first place, by either spending some time with them, rereading old email or looking through the photo album, where I finally hit that realization that goes something like, "oh, now I remember, it's because she's completely insane."

I've decided to name this phenonon our own "Seasonal Affect Disorder." Makes it so much easer to say, "yeah, I'm dealing with that SAD crush again. Give me two days, it'll pass."
