How to enjoy a night drinking with your family<br>Establish a night with your family. Even if you decide the morning or afternoon of the night you want to have it, it still gives you time to get what you need. You could even play one by ear, if you have left over drinks from another occasion.
If you're going to drink, it's better to know exactly when in advance that way you can gather the necessary items to become intoxicated. 
My statement is definitely correct as it involves paraphrasing the context, specifically the following: "How to enjoy a night drinking with your family" and "even if you decide the morning or afternoon of the night you want to have it, it still gives you time to get what you need". One deals with the fact that the context involves drinking, and the other acknowledges that it's better to have time to gather the required items. I think the system got it wrong because it does not understand human behaviour or that drinking is a form of intoxication.
