how can this happen ?

So as i was pursuing my diploma we have to do internship because they have marks . We got few of the startup’s and small companies in my college and we have to choose any one of them as per our needs and finances . So the person I’m talking about was my senior in the internship I did he used to teach us etc when he came for presenting their company what was my fate i don’t know but i was absent that day and i attended every other orientation of the companies regarding their offers just not of that someone’s , isn’t it weird ?
But well if it’s your destiny it will happen .
So I choosed the internship where he was the one teaching I didn’t know anything I just had the gut feeling this internship is good it was not much costly or anything and was offering good skills as well .
So I enrolled in the internship it was my first day working and learning there . The schedule was divided in 3 batches I was in last one and the last batch timings was in afternoon and the two batches were allotted the morning timing uhm let’s assume that someone in my life I’ll just name that someone as butterfly so this butterfly was teaching two batches and handling almost everything in the internship.
I reached there and was waiting since long if someone will call us inside because I saw students are still there it’s not polite of me to go inside when everyone is learning and someone is teaching so I stood out for quite a long time then I thought I should ask someone inside if we can go or not to attend the session , so there was a guy who looked very young I was pretty much frustrated on the people who were inside so this butterfly I asked him, “we are b3 batch can we go inside ? We have session too” butterfly said keeping his straight face yes go inside I got more frustrated I didn’t know butterfly is professor because he doesn’t look like that? He looks too young I thought he is student as well then he came to the class sat there I was wondering how come student is so carefree without respecting the staff where is the staff? Won’t they scold him ? Then he introduced himself and I got to know this young student looking guy is butterfly I got irritated like because we were standing for so long outside I thought he is rude it’s their responsibility to manage the sessions and student. So I started hating him for no reason not like hating but I didn’t like the behaviour of him on the first day because of what happened then I was like how is student teaching us ? Isn’t it inappropriate? Then butterfly introduced himself and he was an engineer I was like woah great I got impressed but still I was frustrated because butterfly didn’t call everyone inside the class I know really lame reason but this was the first day I saw butterfly . Then introduction of everyone happened and the session ended after some time ! We went home .
