That's between you and I

[Backseat Driver]

19. Question everything, LOL!

Here's the rules on how to use question marks; be sure to also view the link at the very end regarding terminal punctuation. I believe you used the question mark appropriately in your post because "me" is italicized as the specific word to be acted upon as the suggested action of the whole sentence.

BTW, there are rules about the how and when to use the idiomatic "how about" as well.

Just between you and me, lol, just because you hear it more and more often does not magically turn using I into proper usage in that instance.

Here's a question for You, the All Powerful I." Are you part of the selfish "ME" generation that wants to abandon punctuation and grammar rules as a separatist, elite power play? Me bows to your infinite superiority in case you name me as a clandestine member of the grammar police.

I'm really just suggesting resources to back up correct usage of the question mark and asking other questions as a friend because I was once told not to use "I seen" because it was bad grammar. That friend said I'd forever be marked as uneducated. Forever after that scolding, I winced whenever I heard it used by others, among many other tabboo ways to speak; hence, my bias grows stronger about people in the same way suggested by that friend and yet most feel it rude to point out others' faults directly to their face, so I digress about whether or not you've sinned by mere suggestion of eliminating "me" from the English language, LOL! Actually, I think I'd figure out your meaning with whichever proper noun or pronoun you choose to converse or put to paper. There are far more important issues that need to be resolved where two or three gather together.
