@PUNKEY,
I recall my mother telling me to respect my elders as young as 4 years of age (I remember bits & pieces back to 3 months old). And being who they were, they probably told me the same thing earlier - for they repeated this lesson many times throughout my early childhood.
I know learning to say 'please' came much earlier than that.
So for the father to say that his child shouldn't learn manners is an excuse.
As other possibilities - the father may :
- be afraid to upset his child, in case his child doesn't want to come and see him anymore.
- want his child's time with him to be all fond memories and no hardship
-------------------------------------
That said, the OP framed her question as the child annoying the #@$@ out of you - and not the father.
Isn't it the father the OP has the problem with? The one who won't teach his child certain manners?
Does his father not, by implication, condone his child disrespecting the OP?
--------------------------------
To allow this, the father himself is lacking specific manners.
edit : my apologies, I had to reframe the wording because I hit reply to Punkey, rather than the OP
