attention issue with facebook users?

[greenish11]

As all you know, there are people out there who often post on Facebook what they do like a couple of times Every Day. I don't really care how many times they post but the thing is I know this person, native english speaker ( it matters later) who constantly asks me if i saw her post and obviously forces me to care in a way of joking. I mean, If I say the truth that I don't personally use facebook often and of course didn't see her post, she gets disappointed and upset every time. It's hard to count how many times i said that. What do you think of those people like her ? Does she have any attention issue? I am an Asian, non-native english speaker. As far as I know people from English speaking countries respect each other's individuality and their own freedom and choices. What's wrong with her? FYI , I am not talking about a teenager girl, she is an adult.
