Lily and the Stag.
James Potter found himself in a hole. His Best Friend pushed him in, even when it was a "bathtub" they had made in the ground for Severus Snape. James looked up, he had been trying to get out for a half hour now, and it wasn't working he just would keep slipping. Then James saw a girl with dark red hair walk by.
"EVANS!"
"Potter what are you doing down there?" Lily Evans asked.
"I'll explain later help me out."
"Why would I do that?"
" Because your head girl and suppose to be helpful, and you love me."
"And your head boy and not suppose to be so thick, and no I don't."
" I'll make a promise I swear, I'll leave you alone and not ask you out for a month if you help me out. PLEASE"
"fine!" The red head got on her knees and helped pull him out. when they were still standing James held Lily's hand.
"Let go, you promised."
"Aw, my little lily-flower. Next time think about who you make a promise too, now will you go out with me?"
"Next time James think about who you break a promise to." Next thing James knew, he was in a hole, again.
