A vegetarian and teetotaler, Modi has a frugal lifestyle and is a workaholic and introvert. A person named Badri Meena has been his cook since 2002. Modi used to maintain a close and publicised relationship with his centenarian mother, Hiraben. Modi's 31 August 2012 post on Google Hangouts made him the first Indian politician to interact with citizens on a live chat. Modi has also been called a fashion-icon for his signature crisply ironed, half-sleeved kurta, as well as for a suit with his name embroidered repeatedly in the pinstripes that he wore during a state visit by US President Barack Obama, which drew public and media attention and criticism. Modi's personality has been variously described by scholars and biographers as energetic, arrogant, and charismatic.
