Sorry. This has nothing to do with instructables, but here is what someone I know said:
"I heard this yesterday on the fourth of July.
'and I'm proud to be an American
where at least I know I'm free'
What is wrong with that?"
Someone I know asked me that question and I do not know. They said it had nothing to do with punctuation or capitalization. I will tell everyone later (if that person will give me the answer).
