Really? Cause some of us like our grandparents, parents and in-laws. I'm just sayin'. If the kid doesn't want to friend grandma, fine, but gradma isn't a freaky boundary pusher for facebook friend requesting her grandchild. I'm freinds with my husband's grandma, our teenage cousins, teenagers in our church. SOME of us enjoy happy, healthy family relationships that aren't frought with hand wringing about boundaries.
I agree!!!!
I never, ever, said that a kid should never 'friend' any relative that they really WANT to.... I do stand by my opinion that relatives, except for parents of course, should not EXPECT to have any right to horn in or interfere.
In this case, clearly, the OP herself, knowing this grandma, in her better judgement, has serious reservations... And, something tells me that this teen isn't begging to 'friend' her grandma either... I think it is completely unbelievable that anybody would have a problem with that, and feels that the the teen should have an obligation or that the grandparent has some inherent entitlement or right.

It's that simple.
I think it is funny that people think kids have a right to adult free Internet interaction. Maybe they ought to put that one in the constitution.
I don't think anybody believes that a kid has a RIGHT to free and private internet communication... That is just another completely absurd and negative accusation...
Personally, my son is not on these sites, and I don't see this changing anytime soon.
But, I won't tell the OP that her daughter should never be on these sites, because, I respect others opinions, and it is her call. Not mine.
She never asked, so I have never made any comment on that topic.
But, IF the teen does use facebook, because the parents have allowed it... It is THEIR communication.. THEIR friends... etc... While I fully believe that parents should have access.... I just feel that anybody, even teens, should be given the respect for their personal feelings and autonomy.
It should be the teen's call....
Unless of course, as in the OP's case, she feels that she needs to protect her child's best interest by making the call 'just say NO'.
But, people can keep up with putting words in my mouth, issuing personal attacks, etc...
This is the DIS dont'cha know.
