Flags at half-staff

While we were waiting to go into the Rec Center for playgroup today, DS1 pointed out that the flag was only half way up on the pole. I explained to him that it was on purpose because a man who used to be president of our country died recently. Everyone flys their flags at half-staff for 30 days to show respect for him. Over an hour later, as we were leaving, he explained to me why the flag was only half way up.
