Heather and my sprained fingure

So this was a few days ago, but i rember it crystle clear. So i had Heather, ((My bff)) over to spend the night. and we went to the park to play basket ball. we were trowing it back and forth to one a nother. and then shooting it when we felt like it. but you see, she threw the ball at me, and i was soo not prepared for it. i put my hand in front of my face to block it. and it made my fingur go ALL the way back words. OUCH!!! it hurt really bad. but, i didnt want her to know. so we kept playing, and that made it worse. so now its 2 times bigger, and greenish/purple... yucky i know!
