Probably my mom. After my dad died, it was just the two of us. She was a kind of nervous type and a worrier and I can recall at a very young age helping her with things. I learned lessons of what to do and also what not to do in situations.
Another one would be my aunt. I moved in with my aunt and uncle when my mom died. I could not stand my aunt, she drove me nuts. But she is still the voice in my head at times causing me to do better and make good choices. Love her dearly now but when I was 15 - NO WAY.
