Mine is along the same lines as Piglet except it happened back when I was in high school ( I say that like it was long ago lol)

Me and my boyfriend had been together for about 2 months and he always walked with me between these two classes (I cant remember which ones). One day I was in my own lil world as I walked and reading something in my notebook when an arm wrapped around my shoulders and someone whispered, “Hey Gorgeous.” “Hey Babe,” was all I said before I stopped to write something in my notebook. By now this person was behind me hugging me with their head on my shoulder reading what I was writing. All of a sudden I hear my boyfriend beside me saying, “Justin, what on earth do you think you are doing?” I turn around to see my best guy friend (the 1 I do all my friendly flirting with) was the person who had been reading over my shoulder. I was so embarrassed that I didn’t talk to either one of them for the rest of the day. We still joke around about Justin being my "other man". LOL!
