No no I'm right! I don't remember what version was (I use messenger since 1999) but surely an older type got this functionality in past (even if some people say I'm fucking crazy, I probably miss some roller in my mind during these years and then I'm going wrong). In past I rarely took part in them but these time my friend discovered this functionality and they're abusing of it too much. However, it's very stressful to close group conversation every single minute, It will be dangerous for my mental health in future I think...aaaargh! Thank You
I believe the only solution is to block most of my contacts for the moment...
Bye
Tomorrow the world cup
