Alcoholic beverages should not be present at a reception for a child graduating high school? Agree or disagree?

They are graduating high school, entering adulthood, in most countries they'd be less than a year away from being able to buy alcohol. Some would be able to.

Absolutely not if it is a public event. Up to the adults present if it a private event and the alcoholic drinks are for the parents and other adults only.

Well, not at the reception, proper, but at home after the reception, that would depend on the age of the graduate.

How will anyone get drunk and flirty without alcohol?

We had adult beverages for the adults, just like in the home.
If you don't have alcohol in your home, then you probably wouldn't have it at a graduation party

if they're graduating high school, they're hardly ever still a child. And 18 is plenty old enough to start trying alcohol.

What kid goes to a reception after graduation??? The best booze will be at the grad party with their friends!

It is the youth's moment to celibrate, not the adults. The parents should have a plan for their kid's graduation, taking the kid where it wants to go and doing things it wants to do.

I am fairly certain that my dad did give me a beer when I finished secondary school.

We saved the alcohol until the party after the reception

Of course there should

I agree.
