Standing in a shop debating which toothpaste I wanted when two girls - early 20s I'd guess - stood next to me looking at toothbrushes.
The conversation went like this...
Girl 1: "I couldn't brush my teeth this morning so want to get a cheap toothbrush so I can brush my teeth when I get back to work"
Girl 2: "Why couldn't you brush your teeth?"
Girl 1: "My toothbrush wouldn't work"
Girl 2: "Wouldn't work?"
Girl 1: "No. Batteries were dead."
Girl 2: "But why couldn't you brush your teeth?"
Girl 1: "The toothbrush wasn't working, it needed new batteries and I didn't have any"
Girl 2: "But you could've still brushed your teeth with it"
Girl 1: "No, I just said, the batteries were dead so it wouldn't work"
Girl 2: "You could've brushed your teeth with it without the batteries, it's still a toothbrush."
Girl 1: "Oh yeah. I didn't think of that..."
At that point I had to walk away I couldn't keep a straight face any longer 
Me too, Towery!
The best bit was the look on the friend's face.
I don't think she could believe it either!
ah gawd,......... never mind the youth.... thats like something i would do WWW 
Probably the same person I saw on the Victoria Line a couple of months ago.
She was standing facing the back of the train when the announcements came on saying "The next station is Warren Street; the doors will open on the left hand side of the train."
She turned to the doors on her left... 
If her other 'item' had run out of battery... She would have still used it.....
