My current plan is that when our parents leave, me and my buddy are gonna down them then and then our parents wont be back for around 4-5 hrs, in which case we'll be sober enough to atleast pass since we'll be on our way down, they don't usually talk that much, just maybe ask what we want for dinner etc. Is this plausible or is it a bad idea? This is ~3/8ths I believe. Costly out here though. About a hundred bucks. Sorry for low quality, taken with my phone.
