That makes Hopper smile and for a second he's able to forget everything he's left behind. It won't last, in a few minutes he'll be back to missing Eleven, to wondering how she's doing, hoping she's taking care of herself and eating properly, not just waffles and candy. But for now, for just a second, it's okay that he's here.

He takes his phone when Lucy hands it back and tucks it into his pocket, reminding himself to look at it later and figure out how to actually use the thing so he gets to give her a call and arrange for this dinner. It would be too bad to miss out on the opportunity because he can't figure out the technology, but he has to think someone would be able to give him a hand. Maybe Lois, because Steve and Beverly have about as much experience with these phones as he does.

"I will," he promises, still smiling. "I'll, uh let you get back to your grading for now, but I'll call you soon."
