Muhammad: did you know that apparently there's something called "quarter-life crisis"? :D
David: sounds like buzzfeed crap
Muhammad: no, check this out, it makes sense 
Muhammad: <file_other>
David: still not convinced
David: you can deal with all of these disappointments at different age
Muhammad: don't you think there is a certain tendency...?
David: umm to me it's just too far-fetched
David doesn't like the idea of the "quarter-life crisis" Muhammad shares with him.
