Because after all, what are women for? From [1] AP, with thanks to OBH:

A farmer fatally shot two of his teenage daughters in a remote Pakistan village after one did not immediately serve him a glass of water when he returned from working in the fields, police said Friday.

The 47-year-old man shot his 18-year-old daughter for failing to give him water, and then killed his 16-year-old daughter when she tried to save her older sister, local police officer Mushtaq Warriach said.

The incident occurred Thursday evening near Sargodha, 300 kilometers (180 miles) northeast of Multan, a main city in the eastern province of Punjab.

Warriach said the man told police he "felt insulted" when his daughter remained seated after he asked her to get water.
