How do I stop certain Facebook friends from seeing posts I make on other peoples Facebook pages?

I dont want to block them. I just want don't want certain friends to see what I'm posting on someone else's page. Facebooks explanation or instructions are confusing. Please help if you can. Thanks

You can't. Only the people you're sending posts to can limit who else sees what's posted on their wall. If you really want to talk to said people without anyone else reading the posts, just message them.

In the bottom corner of your status there is the audience thing. It is usually public, friends, friends of friends, or friends except acquaintances. You can click on the arrow and choose "custom." There you can type in the people that you wouldn't want to see your status.

You will not be able to control those who can see your friends status even if you are the one to post them unless you post it on your own wall.
