Yes, you’re right. My bad. I totally missed reading the title, except for “manners.”
Which reminds me: “Don't talk with food in your mouth”.
And “Do what you said you would do.”
And the three laws of the universe my kid's have learned:
The VERY first, and foremost is:
“Life isn't fair”.
As they get older and encounter difficulties:
“It's always something.”
and
“Nothing is easy”
Heh. Maybe it those can all be summed up as “No Whining”. We had that homemade sign on our bedroom door for many years!
