Math tells us three of the saddest love stories:
Of parallel lines, who are never meant to meet.

Of tangent lines, who were together once then parted forever.
And of asymptotes, who could only get closer and closer, but could never be together.

"I fell in love with you.

Not for how you look, just for who you are.

We find love when we find an imperfect person perfect.

I love all your imperfections; all of you."
