Pain-ing

I'm injured.

Well not really injured injured. But still.

I'm Pain-ning. (I was told this isn't a real word but in this country, anything goes)

My right arm, upper thighs, and butt ache from badminton.
(I know I didn't play as much but my stamina IS that bad)

My abdomen area aches from sit-ups
(I did about 12, I believe)

I have to do something bout my ridiculous stamina.

But there's always some excuse I'd cook up to pacify myself.
