We had a family with two little girls over for breakfast Saturday. The oldest is around three and a half or four years old. I served them orange juice to drink, but milk was also on the table.
She finished eating breakfast and drank her glass of orange juice.
What she did next astonished me with it's complex thinking and common sense; she took her napkin and thoroughly wiped out her glass. Then she held it towards me asking politely for some milk. Creative problem solving with little or no bother to anyone. Brilliance at the breakfast table.
I'm married to a farm boy who has a barn full of common sense. I admire this kind of smart more than any other kind. It's practical and useful every day. Working knowledge.
Go little girl; you'll go far in life and relationships.
