When I was kid, my parents didn't own a car. This wasn't rare for inner-city families; my dad took the bus to work and my mom stayed at home with me and my brother who is about 12 years older.
Every other weekend when my dad got paid, he would give my mom money to go grocery shopping. My dad would buy fresh meats and stuff from the meat markets on the way home but larger shopping for laundry detergent, cleaning stuff, cereal, etc. we bought every other weekend at the grocery store. The grocery store (which I had to look up because I always thought it was much further) was about a 1.5 miles away from my house. A mile+ in an inner city is far; especially as a kid as it cuts through several neighborhoods.
I was about 5 or so because it was the summer after Kindergarten and before 1st grade (I remember because I took those in two different schools). My mom would only take me with her because my brother wouldn't go through the neighborhood route my mom took to the store. I was too young to know why but learned later my older half-brother (dad Irish/mom Italian) would get his ### kicked at school because my mom remarried to a black guy and had me - I simply went through school with no one making the connection between me and my brother due to us looking nothing alike and years apart.
Anyway, we got to the grocery store as we've done multiple times. And multiple times I would lose my mom; I tried keeping up with her but I would always end up at the front desk asking them to call my mom over the loud speaker. It was so egregious I could sense the frustration from the people working there once they saw me wondering up to them alone. This one time, mom never came. We waited and waited. The woman at the store said maybe she went into the store next door which was a Woolworth's if IRCC. So I walked next door, went to the front to ask for them to call my mom - same story there, they recognized me but no mom.
I went to every store on that strip that day, then after a while decided to just walk home. I got home and my mom was sitting in her room, I jumped in front of her like "surprise!" and she had this "WTF are you doing here look?" - I'll never forget that look.
Not sure if she ever intended to abandon me or what but fast forward 30+ years she's since been diagnosed with mid-stage dementia.
Today, I think a parent that did this would be brought up on charges (or at least shamed), I think we were just living in different times then.
