I don't like shopping

I hate shopping.

My wife and I were in Primark. I'd already been phone-zombying on her shirt tails for a good five minutes when she dragged me from my cyber reverie...

Wife: Balls!

She had spotted some Harry Potter branded Christmas decorations. A four pack of baubles.
 

Me: You want Harry Potter's balls dangling on our tree?

Wife: Let's have a pair.

She picked up two packs. 

Me: Technically that will be four pairs...
