If all the girls still had friends who they saw frequently, and socialised with peers their age at clubs, they would be acting more their age.
It is like they are stuck in the age mentality they were when they were taken out of school. It is incredibly sad to watch.
My son has a 16yr old girlfriend, and she is always out with her friends, shopping, getting her nails and eyebrows done, cinemas, eating out, works and is at college. My son and her are due to go to Winter Wonderland soon too. Normal teenage stuff.
I know Issy isn't at college yet, but everything else I listed is what most teenage girls are doing. Even when I go to the town shopping, you see groups of teenagers (boys too) shopping and enjoying themselves. I saw a group of 7 lads of about 15/16 sat in Cafe Nero all joking and laughing with each other over the weekend.
Even my 14 Yr old goes out most weekends with friends, playing football or going for lunch/to the cinema.
