Horse sense is good sense!!
little kids know too, I sat at a stop light down town recently and noticed two men walking down the sidewalk holding hands, a lady with a small boy 3-4 years old coming from the opposite direction and when they passed the little boy did a very obvious double take and then a third time looking behind him. The mom holding his hand made eye contact with me as I sat there grinning in my car. She acknowledged me with a slight smile and eye roll. Smart kid you have there ma’am I thought.
