Some kids get so stressed by this type of thing they commit suicide, and so do some adults it is not about age it is about how you deal with things, what things have affected you sometimes as a child mould who you become as you grow up.
The twins do have each other, they also have that Irish thing, not sure how to explain it but look at Terry Wogan he takes it on the chin and always has and is able to laugh at himself, I can think of many Irish with the same type of armour I guess you would call it.
Danyl is not that type of person if you ask me, he is very vunerable as are a lot of actors, singers, painters they wear their hearts on their sleeve and the hurt shows no matter how they may try to smile it away or shrug it off, it does not mean they are not good at what they do, they just dont handle this type of thing as well as others. To be fair to have this type of thing in the magnitude that he has beggars belief as to how many would deal with it.
For me he needs to not say anymore over there, just ignore these idiots as that is all they are, faceless idiots hiding at home, feeling big behind a PC screen.
