Me: Is it doing anything? What did you do?
Vistor: No. I pointed my phone at it like you said. Then I took a picture.
Me: What app are you using?
Visitor: The photo app I always use.
Me: Can you be more specific?
Visitor (showing where the icon is): That one. I always use it.
Me: That one sucks. Do you have any others?
Visitor: I don't know. There's photos in the Facebook app. Should I try that?
Me (grabs a piece of paper from the fridge, exasperated): Here. This is my wifi info. Use the 5ghz one. If that doesn't work, try the other one.
Vistor: Oh, ok, whatever. Thanks.
