Joanna: Mom, can I sleep at Jenny's tomorrow? Please...
Sandy: You know the rules. What did Jenny's parents say? Are they okay with it? 
Joanna: I asked you first, Jenny and I, we talked and there's this concert we wanted to go to and we would come back to hers after the concert and sleep at hers...
Sandy: wait, what? concert, you said sleepover, not concert!
Sandy: what concert? Where? who'd be driving you? why do I hear about it one day before?
Joanna: This band I told you about, the guys from Korea, BTS, they'll be in town tomorrow and I really wanna go and you know Jenny and I love them. You got me that t-shirt for X-mas, remember? And we wanna go and Jenny says that when you say yes, her parents will say yes too. Please, can I go?
Sandy: Absolutely not. You've known about that concert for weeks and you come to me today? No way. 
Joanna: but Mom! I really wanna go, you won't have to buy me a present for birthday this year. Please...
Sandy: No. Way. One, I've already said no to that concert, Two, you asked me about sleeping at Jenny's, Three, you wanted to trick me... No. 
Joanna: no, I really want to sleep at Jenny's. Can I at least do that? No concert, just sleep there?
Sandy: I am angry at you, you know I hate when you try such things. 
Sandy: I'll call Jenny's parents and let you know later. 
Joanna is asking her mom Sandy if she can sleep at Jenny's place after the BTS concert. Sandy does not know about the concert but Joanna believes that she told her about that. Sandy is upset and thinks that Joanna is lying. Sandy will call Jenny's parents and will let Joanna know later.
