My love-hate relationship with cake

So it happened again yesterday. I was passing a bakery when I saw a gorgeous slice of cake. I should've known better as, the majority of the time I have eaten there, I have often been disappointed. But, I bought it. The first bite was amazing--everything I hoped it would be and more! The second bite was still good, although not nearly as great. The third bite started to taste waxy. After a few more unenjoyable bites, I threw away the slice of cake without finishing it. Why does my brain discard all the information it has gathered when I see a delicious-looking cake?

I'm starting to think that's what I've done with men too.  *sigh*  Since I'm resuming interest in dating, I need to examine why I do this and fix it.
