There is an interesting example of boys and girls thinking. It happened to me.

He writes to her:

I think about what will make me happy and what will earn me money.

I think about sex

I think about what I can do to be as efficient as possible.

I think about what I don't want to spend money on

I think about love and if I will ever find a girl who can love me for who I am

I think about sex

I think about other cultures and other kinds of people

I think about the future

I think about computers

I think about cars

I think about fighting people

I think about sex

I think about video games

I think about the past and try to learn from it

I think about death and if I will die alone

I think about racism and how to fight against it

I think about my family and how I must one day leave them

I think about other planets and what it would be like to go to one

I think about music

I think about sex

I think about food

I think about clothes

I think about friends and why all my friends are gone

I think about art

I think about God

I think about you
I also sometimes think about sex :)

This is what she writes in response:

I think about God’s justice and grace

I think about right and wrong trying to define those for myself

I think about how hard is it to stay clean in my thoughts, words and actions;

I think about how selfish I am

I think about how I should behave in different situations of life

I think about criteria that would be right to measure my actions/decisions/feelings against

I think about my parents, my brothers, sister

I think why there is nothing easy in life

I think of why most of things that feel good and easy now usually have negative consequences in future, and if it’s hard now it turns out to be good in future

I think about many questions that don’t have one answer and try to define my position on them, and establish solid reasoning behind it.

I think about Ukraine and my friends there. Sometimes it feels so unfair that they can’t come here

I think I should become more responsible but I don’t want to

it's just interesting how people are different
