The sentence I used can be ended with a question mark, an exclamation point, or both, because it is an interrobang. Also, you should never start a sentence with the word so, but thanks for your tip. According to Microsoft Word Processing it is fine to end the sentence with an exclamation point anyway. As for getting a life, I already have a very nice one.
