I will share something funny one guy said about me. Do you also feel it was funny?

Yesterday in college, when me and a guy from my class named Guru Kishore were walking around, we saw our juniors who were in 1st year walking around. We are in 3rd year and I asked Guru Kishore 'do you think they will get scared of me if I tried to chase them for fun?' Then Guru Kishore said 'no they will kick you.' But then I said 'I am their senior. I am 20 and they are like 18 so I should defeat them in a fight.' Then Guru Kishore said 'just look at them. They have full beard and all so you will look like a child near them.' Yes its true most of those 1st year boys have beard and look much older than they are. In fact I look and act more like a 1st year student than they do hahahaha.
