<human>: This was at a part time job I had a couple years ago. Being a naive 16 year old, I had no idea this person was preying on me. This person tried to take advantage of me. He was really creepy and he added me on an app called WeChat. His wall had pictures of me while I was working. I didn't think much of it at the time.

Some of my coworkers and I went out to an after work dinner. He forcefully grabbed my hand that day. I didn't say anything at the time. He would harass me and spam my phone. I ignored and blocked him eventually. I quit my job too. I couldn't handle this creep.

I'm so disgusted by this. I remember it and I'm so upset. What should I do? It doesn't even seem like a big deal. It shouldn't even be a big deal because it was only the hand, but I get so angry when I think about it. I wish I spoke up. I wish I yelled at him. It seems silly, I know...

Give me a shortened version of the text
<bot>: How can I control my anger about a person harassing me? He's not in my life anymore but when I think about it, I get so angry.
