Me: Did you enjoy your bath?
Jen: Yes thanks.
Me: You've put perfume on. That's unusual.
Jen: I haven't put perfume on.
Me: Well what's that smell, then?
Jen: It might be my shampoo.
Me: [Sniffing Jen's hair] No, that's not it. It's more pungent than that.
Jen: I think you'll find that's Tesco bath cleaner.
