'Cause we were just kids when we fell in love
You've known Grover was the one for you since you met him at your elementary school. He was your best friend and he always stuck by you. He was always the (weirdly) tall and skinny kid that got bullied, and you were his best friend that always protected him.
Not knowing what it was
You didn't realize until just about a week ago just how utterly head-over-heels in love you are with your best friend. You just started noticing the way his laugh lights up his face, how when he smiles it's always with teeth, how he has dimples when he frowns, how he randomly remembers to correct his posture and randomly straightens up. You've noticed a lot of things.
I will not give you up this time
You just love him. And he has no idea. It's awesome (100% most fun thing ever).
But darling, just kiss me slow.
You just want him to wake up, remember he's in love with you and let you run into his arms and never leave.
"You okay?" he asks. You two were talking about a hiking trip when you zoned out. You noticed he tapped his hoof against the rock every three seconds.
