What to say if she asks "Who else is coming?"

I think the title is enough... what to say if you ask her to hang out in the way of "I'm gonna buy some 'cool stuff', wanna come?" and she says "Fine, who else is coming?"

I know there are different ways to ask the question, but I was wondering about answering THAT question of her, just out of curiosity.

What like people other people have to go if u ask her to the mall? Thats basically a lame sh1t test by her; if you got friends she should know!

Make up something totally outta hand, like ya I'm meetin Wyclef at Famous Footwear, we was gonna pick out some new sneaks together then hit the Juice Stop, haha. It'll probably make her laugh, then have a Bounce plan from there.
Hope that helps!

Yeah I know, it sounded a bit like a sh1t test, I meant it more like if she asked it more subtle, in a honest way (as if I didn't make it clear), not as much as in a sh1t test.

Wait so did you ask this question yet or not? Because I wouldn't ask it that way.

Be more authoritative.

No no, I meant what I said sounded like if it was a sh1t test, and something slightly similar happened in the past, that's why I was wondering.
And about being more authoritative, I think it's a good idea, not overdoing it, but I'll probably do it.
Thank you!
