I'm thinking of taking pictures of high schoolers playing on a playground meant for much younger children and trying to get their teacher fired
Could you explain this to me more? I don't get why you would want to get their teacher fired?
I just want to get back at this teacher for being so mean to me in high school.
It sounds like you have some unresolved issues from your high school days. You shouldn't post pictures of others online without their permission. It will just start drama and on line harassment.
I'm going to find some photos of them playing on the equipment and police don't care.
You shouldn't post this stuff online, you're not only going to ruin the teacher's life but some of this could be traced back to you. Do you want this to be what people think you're all about?
