It is the epitome of a text conversation that leads to no productive result at all. Very short and point less. It might seem like the person texting you wants to chat with you, but in reality it just leaves you with an awkward silence.
Person A: Hey, what's up? You called.
Person B: Yeah. Nothing, just wanted to see how you were doing.
Person A: I'm fine thank you! How are you?
Person B: I'm fine.
