Input: I'm off work for a week and thought it would be a great chance to go and visit some family. I hopped on the charter bus and as soon as I did, I heard an eruption of laughter coming from the back of the bus. I look up only to find the girl who used to bully me in high school, staring directly at me, and laughing to her friend. I haven't seen this person in 5 years, I've made no contact, I've blocked her on all social media platforms. This was a bit jarring but I took my seat and put my earphones in. 

I made a post on social media about the incident, along the lines of "I havent seen you in 5 years, why are you carrying on with the same shit". 
I thought my friends would find the situation funny. 

One of the other girls she used to bully had commented, asking who she was. I reminded her and we had a laugh at the bullies expense. I made a remark about her not changing since High school.

This girl, was horrible, inside and out. I had a month of school because my Uncle, who I was very close to, passed away and I didn't know how to deal with it. It was around that time I was diagnosed with GAD (Generalised Anxiety Disorder). I went back to school somewhat confident that I could manage my emotions. I was wrong. I walked into class, got my stuff out and was ready to get back into it. The bully knew of my  situation because her family knew my family. She kept asking me how my holiday was, she kept making fun of me for being weak, I removed myself from the sitaution, and subsequently had a panic attack in the bathroom. 

Long story short: I hopped on a bus on my way to visit family. A girl who used to bully me, laughed right in my face and talked shit about me to her friend. I made a facebook post about "people not changing" to which one of the other people this girl bullied commented on the post. We made fun of her and how she used to treat people. 
Am I the Asshole?
