<human>: I'd like to preface this with the fact that I've had a lot of crazy experiences in my four years living in NYC. Maybe I'll get around to posting some more of them, but this happened last night so it's fresh in my mind. 

I had an interesting experience last night as I was walking to my local YMCA this evening, in Manhattan. I had my headphones on, music loud to get in the zone for my hip hop class, when I felt a forceful push on my left shoulder. (I should mention that I'm a 5'4", 21 y/o female) I look to my left and I see two kids that look to be middle school age, eighth grade at best. One of them was starting back at me, so I took this as his acknowledgment that he had been to one to strike. Disconcerted, I shrugged it off, turned and kept walking. A mere few steps later and it began: they were *pelting* me with with snowballs! As in, **rapidfire**! I kid you not, there is no exaggeration here. Stunned and unable to escape I just kept walking. I mean, what was I supposed to do? I'm a nice girl, minding my own business *completely* trying to get to my dance class. It was about 7pm and there were plenty of people out, yet no one even seemed to notice. That's the bystander effect, for you. So I stopped in front of the doors to the Y and pulled out my cell phone to make a phone call before going through security to get in the building and I see the boys approaching, clearly carrying more ammunition. The one I had assumed to have pushed me initially had this crazy death glare aimed at me, but when they got closer and caught a glimpse of my phone they dropped their weapons and ran for the hills.

Can you give me a shortened version of the text?
<bot>: I was assaulted with snowballs by two random youngsters on the Upper East Side who fled the minute they thought I was calling the cops.
