As much as it should be the right thing to do to just say 'Next' and move on , K makes a good point .

Every girl you meet and you connect with is different . This is a great thing because you get to experience them in all their unique glory , they can take you somewhere completely different . So in this respect i think it's alright to be dissapointed if you get a flake because you are missing out on an adventure so to speak .

So while you should be saying 'Next' ! Dont feel guilty or less of a man to feel dissapointed as you are missing out on a new adventure and what is a man if not an explorer in seach of new adventures !

Best cure for a flake ... Go out and find new adventure !
