I think this is probably going to be a characteristic of close emotional relationships such as you might have with friends, which explains my next clip, which is of a YouTube video of some young men in the former East Germany on making a video to promote their heavy metal band, and it's extremely macho, and the mood is very serious, and I want you to notice what happens in terms of laughter when things go wrong and how quickly that happens, and how that changes the mood.
See on iseloomulik ka teistele emotsionaalselt lähedasele suhetele, näiteks sõprussuhetele. Sama loogika alusel saab seletada ka järgmist klippi - tegu on YouTube'i videoga, kus endise Ida-Saksamaa noored teevad promovideot oma heavy metal bändile. See on väga macho ja karm klipp, aga pange tähele, mis roll on siin naerul, kui asjad vussi lähevad pange tähele, kui kiiresti see käib, kuidas meeleolu muutub.
