From teaching his sons how to rustle up a meal to taking them on vacations, it's no secret that Hrithik Roshan is a hands-on father to Hrehaan and Hridhaan. Recently, on Hrehaan's birthday, the actor shared a heartfelt poem to instill values of courage and fearlessness in him. Now, Roshan has devised a new way to impart life lessons to his boys - the doting father has been designing comic strips that narrate stories with important moral values.
