I dunno about what gap you're talking about but it's pretty good.
Between when you can have your parents give you alcohol and when you can buy it for yourself you can't drink
Also my man you aren't gonna get drunk I'm pretty sure your parents won't let you do that.
You don't know my life! Or my parents! (My dad drinks in moderation and I don't plan to get DRUNK drunk, just "hey, I'm kinda drunk, I should probably not drive and stuff" sort of drunk. No, they won't let me get DRUNK drunk, but there are parents who don't care if their kids drink in moderation.)
Also note that it's totally legal; it's in my house and if they give it to me, I'm allowed to drink. State law.
