It does not irritate me and why should it? 
I had this friend of mine, she was quite a good friend but whenever she sees me talkin to anyone else (anyone, friends, stranger etc) she would always ask me what was he/she wz saying, kiya huwa..mujhe batao…i wana know etc etc…
And sometimes its very annoyin because there are certain things that i couldnt share with her and she was like “kyon nai bata sakte” mere sai naraz hoo? and blah blah
I always wondered why she was sooooo much interested in my personal life! 
?
And than i decided to stay away from her, (dont know why) and till now i havent talked to her for like 3 months now!
