Subject-verb agreement

I have seen people behave very wild and excited at the Yankees parade. Every body was very happy and excited. I don't think I have ever seen anybody that excited for the Yankee's ( except when they were playing the Angel's and the Philies). They were screaming and jumping alot.They looked very happy. I wish I could have been there I would have been very very excited if I could have been but I was not but I was still happy
