My DD is 18, goes to many parties and they now finish rather later than they used to. We are happy for her to share a can home and so is she. on of her friend's DM is not and ends up picking them up as her DD is scared. She ends up picking my DD up too as they live close. DD finds it embarrassing that I don't take turns. AIBU to think that an adult that is going to uni next year and travels about on trains to gigs in London and other cities is more than capable of travelling home by cab with friends at 1/2/3 am and that I should't feel guilty?
