My mother isn't very good with computers, sure she can type up letters and play solitaire, but anything to do with the internet eludes her, especially when it comes to email...
Mum: I have to send an email to someone I know in England.
Me: Do you have her email address?
Mum: Yes, but she's in England.
Mum: She's in England.
Me: Mum, you can send and check email from wherever you are in the world; it's not like a physical street address with a mailman who sometimes gets drunk and loses the mail.
Mum: Oh. Are you sure?
Me: Yes mum, I'm sure.
Mum: But she's in England, how will it get there?
Me, mumbling under my breath: On the back of a magical email elf that likes to eat peas dipped in cranberry sauce and listens to Enya.
Mum, who thankfully wasn't listening closely enough to hear my smart-assed reply: What?
Me: Nothing, just send the email to her.
A short time later she returns with an accomplished smile on her face...
Mum: You were right, I sent it, and she replied.
Me: No kidding.
Mum: Yes, it's amazing this email thing.
Me: That it is.
