A group of friends and I, we are all in our mid forties, went to a bar a while back and had a great old chat and many wines. On the table near us there was a group in their mid twenties. As we all chatted they all played with their phones hardly talking to each other. Then one would say to the group I facebooked it or something similar. We all found it very strange, they hardly had a conversation the few hours we were there, cheers
