Secretive

Deep inside our core, we have special information that we won't open to others.
Remember when we were little, maybe this works for the female, we exchange information to others?
I did few exchanges with a girl when I was in high school.
It's fun doing exchanges.
"I won't tell you anything unless you tell me something."
But if secret is made to be broken, then that's not fun.
I don't really like sharing deep information; mainly as to who I'm attracted to.
However, I do love giving hints.
That's one of my secrets.
