Three firemen walk by and say "hi" to the girls at the supermarket today.
My girls turn shy and Katie sort of waves at them.
KT: Why do we say 'hi' to firemen?
Me: Because they are good helpers and it's okay to say hello to them.
We pass by the firemen a couple more times in the market.
Later in the car...
KT: How come only women said 'hi' to the firemen in the market? I didn't see any men say 'hi' to them.
