During times of national crisis or tragedy, people will often fly their country's flags at half mast out of sympathy and solidarity with those affected by the events. If you get one with multiple sections, it will be more portable and easier to store away when not in use.

It's an expression of love and loyalty for our country, and it can be expressed in many different ways.
