1. Modern technology.
Technology is an improvement and in essence it's allways good. However we can do a good use or a bad use of thecnologies. At the end is our decision.
People can use it to steal, to damage other people, to defraud, to get rich, instead of to use it to improve jobs and lifes, to find information, to be more safe and healthy. But bad people exists. And they will use good things in a bad way to try to achieve their objectives (e.g. a knive is not a criminal weapon however you can use it to kill somebody).
2. Vocabulary.
The FIVE words most useful for me are: swith, plug, lead, unplug and plug in. Sometimes I need simple things and if I didn't know the exact word I use to build very long sentences explaining that I want. It's always embarrasing!
3. Mobile phone stories.
I always lose my mobile phone. It's not really "lose" because at the end it appears. I phone my movile phone and wait to hear where it rings. It's an unpleasant situation. Sometimes the situtation becomes more stresfull if the sound was turn down because I was in a meeting!
