How do I manage Facebook friends groups?

I have several Facebook friends groups. None of the posts by these show up in my general newsfeed. If I am viewing the posts in one of these friends groups and click on the ‘like’ button, will this ‘like’ show up in any of the other friends groups? For example – I have a few close friends and another group called ‘Office’. Posts by members of either group do not show up in my newsfeed. If I am viewing posts by my close friends and ‘like’ or comment on an item, will members of my ‘Office’ group see these?
