I'm not being funny @WorraLiberty but in 'The Railway Children,' Sally Thomsett looks much closer to 20 than she does to 11. So I am not sure what point you're trying to make.
She looks around 17.
The vast majority of people in their 30s will not look 16-17. Sure, some may look 7-8 years younger than their age, but do will not look 16-17.
Sorry, they just don't. If someone thinks a person of 33-35 looks 16, they need to go to Specsavers, because I have never seen anyone in real life who looks 16 in their mid 30s. From a distance, they may look much younger, (if they dress like a teenager,) but close up, they will look close to their age.
Most people look their age, and The vast majority of people do not look more than 7-8 years younger than their age. That's a fact. People are deluded if they think they look 15-20 years younger than their age, and anyone who says they do, as I said, needs to go to Specsavers!!!
And I have seen some effing rude posters on here, but @Sparklfairy takes the biscuit. What a nasty person she sounds.
