I've been working as a pharmacist for about 5 months now.
I live with my Dad in his trailer in the woods in a rural area. I don't pay rent, and I don't pay for utilities. I do chip in for groceries, etc. and occasionally buy my Dad dinner. My Dad pays for some of my health insurance (Because of Obamacare, I can stay under his insurance a while longer.), but I pay for the deductibles, copays, etc. and all of my other bills (like car insurance).
My parents gave me a little bit of money during school but not much. I went to a public school, got state scholarships and two alumni-sponsored scholarships, and graduated debt-free.
My Dad enjoys having me. He won't charge me rent because he's scared it'd make me want to leave.
I often think about moving out. Staying with him does have downsides. His trailer is not comfortable or classy. Also, it's very awkward to date: Bringing a girl "home" to your Dad's trailer doesn't create a good impression. However, I live in a rural area, and the overwhelming majority of girls in this area are poor, trashy, and uneducated, and many of them are single mothers by age 19. So I've essentially given up on dating for now.
I've thought about leaving, but staying with my Dad has grown on me. Plus I've been able to save almost every dime I've earned as a pharmacist. I pay for food, gasoline, ~$300/month for entertainment and hobbies, and a few bills... All the rest has gone into my savings account. I'm saving up money for something big (not career- or pharmacy-related) I want to do a few years down the road.
