Don't feed the foolishness!

Ok. So last year I was learning how to say "no" and this year I'm learning how to ignore. I'm still struggling with both. My main gripe is this: why don't people get it the first time? When I say "no," I usually have to say it 5 more times before people even start considering that I might be serious. Now, when I am clearly ignoring you, why the hell are you still texting me? It's like this, I told you where I stand many times. You decided to disregard that so I decided to disregard you! Who has time to tell the same person over and over again how to treat them? I am a very clear communicator. So, once I have been telling someone the same thing over and over again with no response, I know it's time to move on. No need for me to re-engage with you and have the same discussion for the umpteenth time. I'm not putting anymore energy into talking to you. I'm not going to feed into your foolishness. I'm done. So ummm, when are you going to get the message?
