Our House: A Sky in the Cloud?

( I have absolutely no idea why there is a white background to my post!!)

Heard on the way home from work. Talking about computers. Yes apart all day and talking computers:
Me: The desk top is going to give in any time now. I need to back it up.
Husband: Huh?
Me: Well it's on its last legs so better done now.
Husband: There's nothing on it.
Me: Photos, files...
Husband: That's true. Put them on an external hard drive.
Me: You've seen the price of an external hard drive?
Mentions cost of one I bought for the office.
Husband: Well you can put them in the sky.
Me: Pardon???
Husband: In the sky.
Me: Sky?
Husband: That thing you're always talking about in the sky.
Silence. Followed by total silence.
Me: You mean cloud?
Husband: Whatever..... I knew it had something to do with the sky.

And this from a man who computer literate, insisted we had computers in our house in the mid 80s, long before they were as common as they are today and long before lap tops.
Sighs.........sky??
