     People of older generations often complain about the selfishness and lack of respect they find among

the younger generations.It is undeniable that some young people do need to be educated on mutual

respect and concern for others, especially senior members of society.But we older people should have

some understanding about the young, too.

     Today's society is rather different from what it was when we were young.The social, financial and

psychological pressure today's young people have to face is much higher than what we did back in the

1950s through the 1990s.

     They are in the early stage of their career.They have to find proper jobs to support themselves and

work diligently to rise.They have to live in smaller houses, because they are unable to afford the soaring

housing prices.Considering these facts, we may find it understandable why young people sometimes

appear aloof and disrespectful.

     I don't mean that we should put up with it without reminding them of the need to mend_their_ways.

What I mean is that we should be more patient, understanding and tolerant toward them.

     For instance, when we get up on a bus or a subway train, we should not complain about not being

offered a seat.A young person does not offer a senior citizen his/her seat probably because he/she has

to travel a long way to work or because the carriage is too crowded for one to move at all.

     In fact, young people do offer their seats to the seniors.I seldom take a bus or a subway train, but

more than a quarter of the times I have done so, I was offered a seat.That is fair enough, given that I do

not look so senile.

     But on occasions, I have seen old people not showing any sign of gratitude when offered a seat.

     China has become an aging society since the end of the last century.According to a recent survey,

people older than 60 accounted for 11.4 percent of the nation's population.And the percentage is

expected to rise, given the onechild family planning policy our country has practiced for more than three

decades.

     In other words, the younger generations will have to shoulder a heavier burden in looking after the

parents and grandparents.Theoretically, there will come a day when one couple may have to support

four parents and eight grandparents.What a burden it would be!

     All this demands that we show more concern and understanding to our younger generations.
