I have a particularly weird view on this so I don’t know how helpful it will be, but I share it when people discuss alcohol.

You, as a person, are basically an imaginary construct given meaning by consistency. Your friends trust you because you consistently behave in a way that says they can trust you. The pattern of behaviours is you because the physical parts swap out all the time. When you drink, you distort yourself a little, because it distorts the behaviour. Anyone who says it doesn’t is delusional. For some people, the distortion is minor. For others, it distorts them a great deal. The drunk you is always so distorted as to be essentially a different person, but one for whom you have total responsibility, because you ‘gave them the keys’ as it were. You are letting the funhouse mirror version of yourself take control of your body so you can be amused by the distortions. Everybody’s mirror is different, but they are all distorted. How much do you trust someone who is much like you, but distorted?
