Flash Marriage
There is a general discussion today about the phenomenon of flash marriage among young people. As it indicates literally, flash marriage describes establishing the marital relationship in a fraction of time, skipping the period of knowing and getting along with each other. Some argue that such speedy relationship may not last long. But people who advocate marriage freedom argue that young people have their own opinion about marriage and can be responsible for their behavior.
As society progresses, people's conception of marriage is changing. Financial burdens of keeping up a long-term relationship before marriage have proven to be too difficult for many lovers to handle. Speedy marriages seem to be more economical. But, flash marriage, or getting married without careful consideration, may cause severe social problems. One extreme example published by a Chinese newspaper goes like this: a young couple married in the morning, argued at midday and divorced in the afternoon. Flash marriage, for lack of mutual understanding, may lead to higher rates of divorce.
In my eyes, flash marriage is not fit for most of the young people. It is only acceptable to people who are mentally and psychologically mature and with a certain economic foundation. It's surely more sensible to know more about your partner before going down the aisle.
