Grandma: so how do I scan that thingy in order to comnect to the wifi?
Me: I already told you that's something that you have to do only once. Just turn on wifi and it'll connect automatically
G: But I already turned it on and it's not connecting. Now tell me how to scan that again
Me: Are you sure that you did?
G: Yes
*Checks*
Me: It's disabled...
*enables wifi*
G: Oh, thanks, it's working now.

Literally every time she wants her phone to connect to the wifi.
