I just wanted to let you know, real quick here: question marks pretty much just go at the end of questions. Or, I mean, like if you're doing some kind of Spanish thing they can go at the beginning of questions too. But the point is that it's always a question. Not like a statement or something. I guess we could do some examples. Would that help? OK, examples!

Good: Are you excited for the weekend?

Not Right: OMG like I am so excited for this weekend!?!

In the second example, you're using syntax to create some kind of verbal inflection that doesn't make any sense. I mean, I'm sure you know what you meant it to sound like -- well, actually, no I'm not.

Anyway, thanks for tuning in. Next week: How to Use the Ellipsis Every Four or Five Words.
