<human>: So this was about seven hours ago when I was still in school. I wanna preface this by saying when I tell stories I tend to be physical in my explanations.
 
Anyways, so after my calculus class let out, I was talking to one of my friends about the quiz we just had and how difficult it was, but somehow it turned into how drunk we got over the weekend (Don't ask me how). As I was explaining the deranged dance I was doing while under the influence, I swung my arms out while walking backwards and smacked this tiny grade 9 (I assume) girl in the face. HARD. I felt bad and tried to find her, to explain and calm her down but I had no luck. About halfway into the last period, I was called to this office, I immediately started to panic and my hysteria grew as I made my way to the office. As I walked into the office and noticed the little girl cowering with the imprint of my hand on her face. Apparently it was quite severe because her parents were there, giving me glares of death as I walked into the principal's office. After a chat with the principal I got off with a warning and but I'm pretty sure I ruined that girls experience at my school.

Summarize the given text in a few sentences.
<bot>: I was explaining a story about my weekend, smacked a girl in the face, ruined her experience at high school.
