The Afghan girls who live as boys
When Azita Rafhat, a former member of the Afghan parliament, gets her daughters ready for school, she dresses one of the girls differently, BBC News reports.
Three of her daughters are clothed in white garments and their heads covered with white scarves, but a fourth girl, Mehrnoush, is dressed in a suit and tie. When they get outside, Mehrnoush is no longer a girl but a boy named Mehran.
Azita Rafhat didn't have a son, and to fill the gap and avoid people's taunts for not having a son, she opted for this radical decision. It was very simple, thanks to a haircut and some boyish clothes.
There is even a name for this tradition in Afghanistan - Bacha Posh, or disguising girls as boys.
"When you have a good position in Afghanistan and are well off, people look at you differently. They say your life becomes complete only if you have a son," she says.
There has always been a preference for having sons in Afghanistan, for various economic and social reasons.
Ms Rahfhat's husband, Ezatullah Rafhat, thinks having a son is a symbol of prestige and honour.
"Whoever came [to our house] would say: 'Oh, we're sorry for you not having a son.' So we thought it would be a good idea to disguise our daughter, as she wanted this too."
Azita Rafhat is not the only mother who has decided to do this.
Not girlish
Many girls disguised as boys can be found in Afghan markets. Some families disguise their daughters as boys so that they can easily work on the streets to feed their families.
Some of these girls who introduce themselves as boys sell things like water and chewing gum. They appear to be aged anywhere between about five and 12. None of them would talk to me about their lives as boys.
Girls brought up as boys do not stay like this all their lives. When they turn 17 or 18 they live life as a girl once again - but the change is not so simple.
Elaha lives in Mazar-e Sharif in northern Afghanistan. She lived as a boy for 20 years because her family didn't have a son and reverted only two years ago when she had to go to university.
However, she does not feel fully female: she says her habits are not girlish and she does not want to get married.
"When I was a kid my parents disguised me as a boy because I didn't have a brother. Until very recently, as a boy, I would go out, play with other boys and have more freedom."
She has returned reluctantly to her gender and says she has done it only because of the social traditions.
"If my parents force me to get married, I will compensate for the sorrows of Afghan women and beat my husband so badly that he will take me to court every day."
