Just a friendly reminder that in English, there are precious few rules and a metric ton (which is a tonne) of guidelines. Style guides do not agree. Dictionaries might not even agree. Grammar guides will agree on most things but not on everything.
What’s a rule?
“Start a new sentence with a capital letter and end it with terminal punctuation.”
That’s about as close to a rule as you’re going to get. And even here there are exceptions. If the sentence is in dialogue, it might NOT begin with a capital letter (it could be an interruption of the previous speaker’s words). The terminal punctuation might NOT be a period, a question mark, or an exclamation point, if the speaker’s drifting off into thought or being interrupted — then it might end with an em dash for an abrupt intrusion or with suspension points to signal the drifting.
No one HAS to follow the guidelines YOU like. And they’re not WRONG if they don’t. They’re making their own choices. They get to do that, and so do you.
Here’s another rule. “An independent clause contains a subject and a verb.” A complete thought contains a subject and a verb (or a noun phrase and a verb phrase, to use different terminology for the same thing). But what about “COME HERE!”? That’s a complete thought, and there’s no noun phrase in sight. That’s because the subject/noun phrase is understood to be “YOU.” “YOU COME HERE!” The subject is clear but it doesn’t appear in print.
If you’re new to this writing thing, do yourself a favor. LEARN THE RULES of grammar before you go breaking them. Having to relearn grammar SUCKS. Learning it and THEN choosing to break the rules? That can be a lot of fun.
I’m all for more fun in 2015.
