Tired

I am feeling a lot better today so I have done more running about. Now I am exhausted. I was a little naughty in the park this morning and had a mad few minutes. I decided that I was going to jump up all over the man that often walks with us and his dog after school drop off. He is quite tall so it was a challenge to see if I could reach his face. I did.
I then ran after someone I didn't know in the park and did more jumping up. My owner was VERY cross but I just wouldn't stop. I made it worse by not coming back to get onto the lead. I don't know what came over me.
I was so much better behaved on my walk this afternoon. I met a 7 month old pup and we had such a great time together.
