Red telephone box

The photo shows pretty famous Red Telephone Boxes of the UK. Sometimes "pretty famous" means only among the foreigners, and I guess the red telephone boxes are no exception. How come I say like that because one of my young female English acquaintances had said that she had no idea why a lot of tourists want to take a photo of a telephone box. She said she didn't feel anything to see them. Well, it happens. People see the same things from a different perspective, that is why life is interesting. I see the UK's red telephone boxes as the prettiest public phone booth I've seen in the world.
