As soon as Alison is finally distracted, I'm going to slip something in her drink.
That's dangerous, why would you want to drug your friend?
Alison will be extremely drunk and it will be hilarious.
That is not a good reason to do that. You should never slip drugs into someone's drink if they are not aware of it.
It's fine and I already laced her drink.
Not only is what your doing dangerous, it is also illegal so you should stop doing it if you don't want to get into a lot of trouble.
