Necessity or Luxury?

When we look at a thing of our favourite, of course, we would like to own it.
But, my dear friends, please don't buy it straight away. Put it down and wander around first.
After thinking twice, you will know whether the thing is a necessity or just a luxury item.
Whether the thing is a necessity or luxury, it depends on a person's needs.
For example, for a computer enthusiast, for sure computer thingy would be a necessity rather than luxury.
