How I fell for you

A poem.
A love poem, actually.
The phases or
the step-by-step process in which -
a girl falls in love - is best described in the poem.
Basically, when a girl falls in love, she does not have a single idea if
it's 'love' or not.
But, once a girl realises that, then
no one else has a single idea that
she's head-over-heels-in-love with someone.
