It was always in moderation. Typically only one drink, maybe two spread out over lots of time if we were fishing. He talked openly about keeping drinking in check. He even addressed alcoholism in our family history, admitting to keeping a close eye on his consumption due to those predispositions; stressing that I'd have to watch it too. Since I was a young kid who felt privileged sippin' on a Highlife I listened closely taking a lot away from those conversations.
Fast forward to HS/college... never drank in HS because it was primarily only losers who would drink at the time... and in college I was always the party nurse or DD because I wouldn't drink to get drunk - I just didn't see the point. Dad had took all of the novelty out of it for me.

Kids who come from overly strict or controlling parents often have behavior and moderation issues once leaving the nest. Your #1 goal as a parent is to engage them and teach them how to navigate life in careful and healthy ways vs. trying to outright control their behavior. Hard truth is you're not always going to be there - my dad died when I was 14. Being an authoritarian doesn't give your kid a healthy mental framework to help them through life's complexities, you're only teaching them to be afraid of punishment and consequences.
