well EsperanzA thats a very nice question
and I'll tell u about something:
in this life we grow up and days are running too fast, when we young or kids, our parents teach us few things to help us identify whats right and whats wrong, and not all what they teach us will be right and of course not all will be wrong, but by time we r growing up and we move on our way in this life and we watch and learn by time,
and by time we start to have our own believes, own ideas about everything and our own characteristic
and like that we r permitted to do whatever we want in our life cuz we r old enough to realize whats good for us, and whats not, of course through our way in this life we might need help from others
we might do few things which is wrong but in the end we all human beings and making mistakes is from our nature cuz in the end nobody is perfect
and its not bad to make mistakes as long as we gain experience from it and we learn also
Thats life
Thx a lot for the wonderful Question, Take Care all of u and wish u a happy life :)
