Frisbee Hiatus

So yesterday after our morning walk, I played frisbee in the park with Amy. Things were going pretty well, except for when Amy threw one of my frisbees in a neighbor's backyard (again!). We had been playing for about 20 minutes when I went to retrieve one and I stepped on something and yelped. It hurt so much! I started limping around. By the time we got back home I wasn't limping so much and in a few hours I was back to normal. Well today we went back out to play frisbee again (Amy even bought me another one, bringing the total up to 4!) but I was scared to get hurt again so I didn't want to play. I'm not sure when I'll return to my frisbee training, hopefully soon. David said if I don't play frisbee, he doesn't want me anymore. I hope that's not true :o(
