Guess, what you would like to do when you sit down with your friends at a restaurant? Of course, taking off your coat. But then? Can't wait to share the latest interesting things with your friends, or take out your adorable smart phone in a rush and then open social medias and check all the notifications? When you look at your friends. You might be suprised to find that she is smiling against her phone, which seems like there are something attractive in her phone make her feel that there is nothing exists around her except her "baby". I have seen another funny person who was scolded by his boss and he looked very nervous. But he couldn't help him to check his phone several times while being scolded. As an consequence, his boss became more angry. But, when he went out of his boss's office, he smiled at once. Because his online girlfriend sent some interesting picture to him. So, do we really need to keep interpersonal relationships in person?
