Jan walked out of his lecture hall, after three hours of maths. Sometimes he still wonders why he chose maths as a major, but he finds it fun most of the time. As he walked, he noticed he got a notification. It was Bojan, his best friend and a sociology major. The text read ‘hey Janči, wanna meet up for a coffe later?’ Jan typed an affermative answer before continuing to walk, until Bojan texted him back, saying ‘btw a friend of mine is coming too, I’ll add you to a group chat with him’
