Today I was in the library at my school when I heard what sounded like sobs.  My ears perked up, as they always do, though I assumed it was just hushed laughter because I was in one of the quiet zones and I have mistaken the sounds of voiceless laughter for sobbing in the past.  When I heard it the second time, I decided it warranted a quick look around, and sure enough a saw two girls walking toward the elevator.  One had a hand clasped over her mouth and was obviously crying, and the other had her hand on the back of the first, gently leading her to the elevator.  Luckily, I was sitting directly in full view of the elevator, though I tried not to make it obvious that I was looking their way.  They turned their backs to me as they waited for the elevator, but I could still hear the sobbing, and I saw the crying girl's friend rubbing her back comfortingly.  The entire incident only lasted a minute or two, but it was a nice break to my studying.
