I have never owned one nor will I. They are another invasion into life.

Someone I know recently cheated on his girlfriend when drunk. He says that if he had been sober he never would have done it, but I'm not so sure. I'm conflicted because we all know that our guard is let down and our inhibitions taken away when we are totally hammered, so is it really necessary to chastise someone ? He is sorry for what he did and his other half doesn't know, but we wanted to settle an argument and see what others thought.

yes it is, the best thing to do is not get drunk in the first bloody place!!!! Why do I need at least 20 words to explain something that is patently obvious?

No

no you shouldn't, live your life happy and leave them
