The cute brunette and the tall blonde...what I am watching here?!

I had just left the main campus library and was walking outside toward my next class. Directly in front of me, about 40 yards away, I see this one tall blonde sitting in the grass with another girl. Then I noticed another girl, a cute short brunette, walking near the other girls.

The blonde yelled out something to the brunette and runs up to meet her. At this point they are about 25 yards from me, the blonde is saying something to the brunette and suddenly they start to make out for a few seconds. In my head I’m wondering what the fuck is goin on and was kinda confused and shocked thinking how my university always preached about diversity.

Then as soon as they quit making out, the blonde hauls off and punches the brunette right in the face! Now I’m really confused! They immediately turn away from each other and begin walking away like nothing just happened. The brunette walked right on past like nothing happened and I still wondering what the fuck I was seeing that day on the quad.
