Wait for my husband/wife/family/friend to get home, so we can decided what to do together. We don't have any enemies per say, so we should be fine.
I'm a bundle of nerves the entire day, checking every lock multiple times and taking a couple practice shots/ sharpening my machete
Make sure there is plenty of food in the house! That's all you really need to do.
Eh, what I do normally during any other day. I mean, the purge doesn't start till 7pm, and I usually make it home before then.
Get all my guns loaded, make sure there's gas in my car, and prepare for my adventures.
