The harsh truth is we hardly care for an unknown person. See around and we will find lots of scope to do something for others but we hardly do it. The people who do it sincerely are very small in number. Most of us have no time even to give it a thought so to do something is a far from reality. If as human we are away from being humane then what's the use of taking birth as a human being.
Sometimes it is not possible to do a lot but I feel one must keep doing a bit for someone regularly. As for example suppose donate an amount to an organisation but not occasionally rather make it a routine, let's say once a month. It helps the organisation properly and it gives a true satisfaction. Helping once in a while is only because of mood swing and no sincere thought is reflected. It is fine when time demands but with it a regular concern is very much needed.
