too mature and too childish

I think my son is too mature for his age...
and my husband is too childish for his age...
faint !
my son lately kept asking me ... if one day me and the father get old and die , would he be left alone in the world ! and after that he started to cry ! very mature boy. and when his pet pass away , he cry like no body business !
as for the father , until now still don know how to plan for himself !
still wasting lots of time ! at time i am quite harsh to him .
it's just like a needle pop into his heart and of course he cant take it.
but what ever i do and say , it's for his own good !
listen to my advise or not , it's his choice.
as a wife , i can only give advise but if the person refuse to take it ,
honestly there isnt anything i can do !
and yes , that shameless person is back in s'pore but if doesnt affect me at all.

as for my new job , so far so good but being a new person in the office ,
i feel like a operator answering the phone call and passing to who ever.
because everyone is waiting for the new staff to answer , sigh !
what to do !
and making new friends is a big problem to me...
because i dont take much and dont know what to talk actually...
so everytime during lunch , i would seat there and listen to them talk ...
