i have a question. how does harassing someone help solve anything? it would only make things worse for her and for yourself. it's true it really doesn't help at all. it would only give you a bad judgement of character in personality. you said that she treats you as if you are stupid. as well as not being able to understand why she doesn't like you. you are proving her point by doing what you are doing. you will find people that will either like you or not like you. just dump her and not put so much of that time and energy on harassing her.
instead you should use and express that kind of feeling into something creative
with your arts, pictures, music, and other things... in the long run when you do this. you will be like "man that kendra girl is so right." this is much better than having to harass someone. that really wasn't worth my time or space.
but believe me i am not choosing any sides here. i am telling you what i think would be the most appropriate thing to do meghan.
