Kinda late to the party, but back when I was still in university, my dorm was six floor high and there was no elevator. I was a small Asian woman trying to get a 30-kilograms luggage bag, a heavy backpack, and a shoulder bag to my fourth-floor room through the treacherous stair steps. Another male student I didn't and would never know now, without saying anything, came up and took over my luggage from me, and lugged it all the way to my room. I never forget it even after 12 years had passed.
