<human>: A little back story: I've known my friend since 2011. She is really awesome and cool, and dating one of my old high school buddies. She got me this job I'm currently working at and she is one of my best friends.

Anyway, today, me and her were stocking shelves on the same aisle, making our typical conversation. I was stocking cookies onto the shelf, and the cookies were on a display right behind me, as the only ones we had in the store were on this display. As I was talking and pay attention to the shelf, I was just reaching behind me from the display. My friend had an item and reached over to put it up, getting between me and the display, and that's when it happened.

Now, when I say I grabbed her butt, I'm not talking about that I brushed it by accident or really got her thigh or lower back. I'm talking about a full-on, full palm, right cheek of her ass butt grab. The kind of hand to butt action you see skilled long time lovers do, or actors in romantic comedies that seem almost too impossible make. The kind of grab that would make Mr. Whipple worry about you squeezing the Charmin. That kind of grab.

She did this sort of half-gasp/half-squeak noise. I knew it immediately when it happened. We immediately stopped. She turned her head very slowly to me and we stared at each other in silence for about 30 seconds. She simply said, "Please tell me that was an accident." I said, "Yes, it really was, I'm sorry." She just kinda turned back around and then walked away and down the next aisle. I turned back around and kept stocking, hoping that she would truly know that I wouldn't do that on purpose.

I ended up with bigger problems. The whole ordeal had been caught on a camera. I got called into the head manager's office and had to explain the whole situation to her and the other manager. I convinced them it was an accident, and my friend told them it was too. But my friend avoided me the whole rest of her shift and didn't say bye before she left like usual. I really think I somehow really bothered my friend, and that really hurts me.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Accidentally grabbed my friend/co worker's butt, awkward ensues, manager saw it but explained the situation, now friend won't speak to me.
