Keys to the front door.
Well, since you must carry a purse of some kind. You need one that you can always stash a beer in it for later! Or a small wine box!
iPhone, lipgloss, sunglasses, cash....
Basically my purse. : )
A lighter, cell phone.
If you are a girl/woman you must never leave home without lipstick or your debit card: I've run away from life enough that I know the essentials.
I never leave home without an ID. If something ever happens I want people to know who I am and where I am from. Second would be my phone. Again, emergency contact in it.
Underwear :)
A pair of pants and a shirt and maybe shoes.
