Mum: I'm on The Facebook page
Me: Right, so on there, what can you see?
Mum: Well, that's the problem - there's a middle bit and I can't see anything
Me: What do you mean a middle bit? A big column down the middle?
Mum: No, just a white bit - a box in the middle: 'no results'.
Me: Somewhere on there there is a cross or a Cancel.
Me: You can tap it with your finger.
Mum: Nothing. It's just all white.
Me: Can you see blue behind the white?
Me: Tap it.
Me: You're sure you're on Facebook? Can you see an 'F' up in the corner somewhere?
Me: Well, you're not on Facebook then
Mum: I am! Oh, I see the 'F'. There's an 'F'!
Me: You should be able to tap the 'F'...tap it.
Me: I don't understand.
Mum: .....What's the 'F'?
