Today's society

I am going to talk about our present society because there are many new habits which  I don't like, mainly the general use of mobile phones.
On the one hand, I don't understand why when people meet to have coffee, to have dinner or whatever,  they are using their mobile all the time instead of  being with their friends. When I go out with my friends and I see they are using the mobile I think we shouldn't have met because we are together but no one is with someone and if they want to use the mobile they can do it in their houses. 
I hate going out to use my mobile, one person should go out to enjoy with his friends.

On the other hand, there is another thing I don't understand, why people, specially young people are always sharing all the things they do: Photos of their trips, photos when they go out, photos of their new clothes...Sometimes I post my photos but only when my trip has finished. When I am travelling I just enjoy my trip.

In short, people should enjoy more all their moments and forget about technology.
