Thank you.
I am 50. My mom only ever worked part time when we were kids and it was either at night, when my dad was home or grandma watched and fed us. We walked to school in the AM, we walked home for lunch, we walked back for the afternoon and then walked home after school. We did not play video games and we played outside until the street lights came on. We whined if we could not go outside. Even if it was snowing!
I think the cause is not lunch!
