Boys are born knowing stuff, like:
Smoking is bad for you.
Don't take sweets from a stranger.
The big kids will take your lunch.
Love is pink.
Only girls play dress up.
Thunder is scary.
Pick on someone your own size.
Football equals God.
Don't break the furniture.
Fire is fun.
Hot chocolate tastes best with marshmallows and cream.
Snow is made for chucking at each other.
In summer you go to the beach.
Birthdays mean presents.
Grown-ups are stupid.
Then other stuff, they learn as they get older, like:
