What would you do if you were lost and alone in an unfamiliar city?

Use the skills i learned playing "Grand Theft Auto"

sounds like everyday life for me, minus the unfamiliar city.
start walking and go somewhere to borrow a phone, something I've done quite a few times lately

Find familiar people. Familiar places. If i had nobody, my first resort would be the public library to get info on the city to better navigate my way.

Contact the police and ask them to help me contact the Salvation Army.

Find a rescue mission or go to the police station for advice.

I'd get involved with a church and move in and do chores for them in order to make up for rent. I'd pray every day and read my Bible and get onto the path of righteousnes, through fasting and prayer.

Knock on your door? Yea it'll be in your neighborhood
