Philosophical mood

They say "don't let a guy come between you and your best friend" but what if you're not in a good friendship and the boy coming along is the wake up call you need? What if you're sick of your friend and the boy is your free ticket out? Maybe you didn't realise that you'd be better off without that friend ... maybe the boy could be your soulmate and passing up an opportunity with him could be the worst mistake of your life ... so in conclusion I disagree with the rule.
