How can I prevent my mom from seeing what I like and comment on on Facebook?

[Jonique Nicole]

I have my mother as a friend on Facebook and I dont want to unfriend her because that will just cause a whole other set of problems.

I have my privacy set so that when i update my status, with either i picture or just words, she and many other family members cannot see them.

However, when I click the 'Like' button or comment on a pages' post or a friends post, somehow she can still see them. I know this because not even an hour ago, I commented on a picture that a band page posted and she commented referring to my comment. I know for a fact that she does not like the band page so it would not have just shown up on her newsfeed. It showed up on her newsfeed because i commented on it. this also happens when i like something of a friends or comment on something of a friends.

so my question is, is there any way to stop the posts i like and comment on from showing up on my mothers newsfeed? i will not unfriend her, and i already have it set that she cannot see my personal status updates.

thanks in advance.
