London: It seems Arnold Schwarzenegger is back to his tough-guy days to teach his children about the environment.
The 63-year-old California Governor is a hardliner when it comes to green matters.
If his children Katherine, 20, Christina, 19, Patrick, 16, and Christopher, 12, forget to turn off a light, they get punished.
“My dad is such a conservationist, if we leave a light on in our room there’s punishment. He takes the bulb out,” the Daily Express quoted Katherine as telling US Glamour.
And Arnie, who is married to journalist Maria Shriver, 54, the niece of former US president John F Kennedy, runs a tight ship.
“The four of us clean our rooms, do our own laundry. The housekeepers know if they get near our rooms they’ll suffer the wrath of Arnold,” she added.
