God Brentwood isn’t the end of the earth and if you’ve such good friends they’d meet near Liverpool Street or Stratford (half hour or 45 min journey across London is nothing for Londoners on a night out) so you could easily jump on the train home. Surely all of her friends have also moved on and aren’t still living in one same neighbourhood?! Most people put the kids to bed and enjoy whatever peace and quiet they have left of the evening after housework, actual work and life admin. Perhaps if Ash’s days were more taxing and fulfilling than eye bleeping herself and getting 90s ringlets done to film herself trying on supermarket clothes she would find some quiet enjoyment in the calm evenings!!
