Millions of people have it rough at night while you have a good nights sleep. These are the homeless people who survive completely on the streets day and night. In the night they turn pieces of boxes, polythene bags, papers into beds to lay on until the sun rises in the morning.
Many of the homeless people are not crazy as they are perceived to be. They have experienced crisis in their lives which have pushed them this far. Some lost jobs and can't afford the basic needs of life any more, some can't afford cheap houses, some lost their loved ones. This gives them no alternative but to seek refuge in the streets which won't turn them down risking their health and safety just to get a few hours of sleep.
The cold gets too much for some that they don't make it through the night due to sickness. No human deserves to live this way however wrong they could be. Though there is nothing much we can do, let's extend help however small to this group of people. Clothes you don't use, extra house-hold equipment, among many can be handed to the homeless to change their lives even a little bit. Some can even be taken in to teach them a few skills they can use to earn a living.
