For a start, I think summer is a good time to hook on something such as a game, a new activity, sport,....because it's maybe when you have more free time. However, you have to do a responsible use of the activity that you are doing. It can cause many problems unless you make a responsible use.
ResponderEliminarNowadays, there is a new game called Pokémon Go, it's probably the best game ever designed. In it, you have to catch pokemons which can be in the street, in a forest, in the water, in a garden.......who knows? It's a really good game because it's virtual and it's a strategy game, although, you must be careful when you are playing it because there have been many accidents due to this game. For example, there are many people that have died while they were playing it. Last week, I saw in the news that a girl died when she fell off a bridge into a river.
Today, I have Pokémon Go on my smartphone, but I don't play much because I don't really like catching pokemons, although I used to watch Pokémon on TV everyday. Moreover, I prefer playing with my brother or with my friend more than with a game.
