Adelaide had a decision to make.
Was it more economical to a) buy a multitrip and validate it every time she got on the tram; or b) buy a ticket from the conducter on the observation that they only got to you about half the time.
Being both an oldest child and one of the few remaining people committed to public health, education and transport Adelaide knew she would go with the multitrip in the end. But every now and then, Adelaide liked to pretend that she was a radical anarchist who thumbed her nose at authority. Just every now and then.
