Hogwarts Letters to Children with Muggle Parents

If my child got a letter stating that he/she had been accepted to a 
school for witchraft or wizardry, I don't know if I'd be happy about 
it.  Does the school assume that everyone who receives such a letter 
will be overjoyed and will enroll their child?  

Or maybe those families who don't want their children enrolled are 
simply horrified, like the Dursleys, and keep it to themselves?

It just seems like a risky business to me when the MOM works to 
prevent the Muggles from knowing about the wizarding world.
