Ohh, come on, teenagers in Bulgaria are still babies. They are used for their parents or grandparents to look after them. They don't know how to do simple things around the house. I was like that - I was very trustworthy and serious and turned my papers on time but precisely for that reason I would not take the responsibility for somebody else's baby - probably the most important thing in the life of any person. What if something bad happens and I don't react properly because I lack life experience?
On the other hand, grandparents have life experience - they have raised children - bad things have happened and they have reacted... mostly properly we would assume...
But, yeah, it's a cultural thing - if we put it in a rather simplistic way - the western world values the energy and the strength of the young people and the eastern (oriental) values the knowledge and wisdom of the old.
