Gawd My son was mowing our lawn as soon as he could reach the handle. My daughter was his de facto babysitter as latch key kids and was doing laundry, starting dinner etc at age 12.
Exactly the same here on the granddaughters at around age 12.
Now the oldest one has her AA degree at age 18 and headed for university next month.
When I was 12 mowing the lawn was my major chore. For a few years my dad traveled a lot for his job. On Monday morning he would tell me “when I get home on Friday that lawn better be mowed”. I could generally be seen Friday mowing the lawn. 😆
