It's simple, Aki. People need attention. It's normal. Sometimes everyone can feel lonely. At that moment, all you need is attention. You need somebody to take care of you. That's OK. 

My opinion is that people have different styles for obtaining information and different styles for getting what they need in life.  Some of us like to be more independent in our investigations, are comfortable searching online, and find Google more efficient, but other people have a style of living for which their habit is to ask others for help as their first step in any process, before they put too much independent effort in.  I think these types of people just prefer to ask, and do not always put much thought into whether they are asking in the most efficient manner.  

Social thinking

I did not analyse much  who they are but i can make a guess they are just a children (very young teenagers  ?)). It is impossible to reach some conclusions why they do it . They are just kids ))
