Question on newsfeed and what friends see...?

[Becki]

Ok, I'll try to explain this best I can. I never see when a friend adds a new friend or when a friend likes something in my feed. But its seems ALL my friends can see when I add a friend or like something, as they reference this to me. I don't get it. I mainly use Facebook on PC and never see "X became friends with XX" in my feed, yet I will get a txt saying "I can't believe you are now friends with XXX". Does this stuff show up more on Facebook Mobile?

I only see when they update their status or check-in, I just NEVER see when they add someone new or LIKE a picture, but like I said, its seems THEY always know when I do and I can't figure out why this is....
example. I go to a friends page and under recent activity, I saw he added 3 ppl 2 days ago, but I was not notified of this at all in my feed, yet friends say it notifies them in their feed when I add someone new.......
