I occasionally use ascorbic acid; doesn't seem to do much...acetic acid is lovely with oil on a salad😋

I once saved a girl from jumping on the train tracks just before the train pulled into the station. I'd never seen anyone on it before and I asked what her problem was and her friend said they were tripping. I originally thought they were tripping as in just being a couple of idiots and they said no they were on acid.
