As a kid you don't notice the fine details of life. When I was young all I had to do was go to school, do my homework and help out around the house, everything else was either done for me or provided to me by my parents.
My mom has been a waitress and bartender for nearly 40 years. When I was a teenager she would work the mornings at a breakfast restaurant, come home and catch some sleep before heading off to bartend overnight. She never complained, never made excuses, never blamed me for how hard she had to work. We didn't have a lot, but we had enough and I never truly looked at the why or the how.
Now that I am the father to four beautiful little girls I can fully comprehend what my mother went through, mind you I am not a single parent like my mother was.
