Boobs To The Face

Here's an awkward moment from BusRider38:

Much like the amusing butt to the face story I have a boobs to the face story. I was on a very backed route 62 headed downtown. I was standing up and letting others sit because it was one of the few times my legs were not hurting. After a few stops the bus thinned out a little and a seat opened up in front of me. The LADY standing in front of the seat seemed engrossed in conversation with her friend standing more to the front so I decided to sit. Just as I was bending over to sit down, her friend noticed a couple of seats that had emptied at the back of the bus and she turned around. Smacking me right in the face with her boobs. I dont even know the proper etiquette, do I say sorry? Does she say sorry? Do I thank her? Or do we both just go completely quiet as does everyone around us? Apparently we all opted for the completely quiet.
