Yeah. I guess it's important to forget about the past but people are being jerks quite frequently.
I guess at the time I argued with her I was being a bit of a jerk but being serious and not making excuses to cover up my ways, it was because I had been hurt by others recently and felt a bit like 'well if that's how they're going to be, this is how I'm going to be'. But I did some stupid things and have learned from my mistakes now.
