I think dad is worried if the house is left to me:

Dad: Were you talking in the driveway when you came home a little while ago?
Me: No.
Dad: Because I heard someone in the driveway.
Me: Yeah, I hear it too. There's a person at the mouth of the driveway talking in her cellphone.
Dad: Oh, did you check who it is?
Me: No.
Dad: Why not?
Me: I don't really care.
Dad: You don't care who's standing at the entrance to your driveway?
Me: No, not really.
Dad: Why don't you?
Me: I really don't care enough to get up. I just want to look at pictures on the internet.
Dad: (sigh)
