How to hide groups I'm in on Facebook?

[RedRose]

I want to join a few groups on Facebook. They are groups I would be embarrassed to join if my friends could see them, because I have a lot of family and work friends on facebook. How can I make it so my friends can't see the groups I join and what I post in said groups?

there is no way to do that

if the group is a public group the only thing you can do is add those friends and family to your restricted list to hide all of your activity from them
