The answer

Love is a gift, not always accepted

Love is a gift, no matter how rejected

You asked if they can, but not if they may

Everyone has their opinion of what to say

They try to deny the truth of the matter

They believe that other believers are like Lewis Carol's Hatter

Love is a gift, not many believe it

But love does not choose who has the best fit

Cupid finds love and does not discriminate

Genders are not considered when he makes his mate

Love is not blind, it sees quite well,

But what we do with it, is like listening to a shell

We hear our own things, and see them differently, too

What we look for is the fitting of the shoe

Love is a gift, unwrapped and fun

Will you fall in love, before your life is done?
