Misinterpreting my posts is not your fault, negative repping me, and getting very sensitive about my posts because you misinterpreted my posts however is your fault. Think really hard, before negative repping or making a big deal about my posts. I don't appreciate being negative repped for reasons that are a result of misinterpreting my posts.
