Wow, Smirnoff Ice. That's some really hard stuff. Seriously?!?!??!! It's like 4% Alcohol. Best prep for the interrogation: where did it come from? Why do you have it? Have you done this before? Do you drink alcohol often? Why? Tell the TRUTH.
Options: no friends, phone, computer, freedom (grounded) slave labor mow grass do dishes etc, Fear of God (yelling, hitting, off to Bible Camp) or if you're a heavy drinker therapy/rehab.
There all possibilities on the table nothing to fear.
