Yikes....INTP's and boundaries. No bueno, nor do we care. I have a great understanding and respect for all. Until 2 years ago, I had no boundaries, not really. I was ok with it. Then people started to tell me I needed them, I will be better off, etc.. that's all bullshit. People set "boundaries" like little gates to keep the annoyances out. You only control your own side. As I hear of boundaries, in this day and age, It makes me think of another way to say "i am selfish", in the way that you control all incoming and outgoing, as per what we think.
In the end, you have no control. That dirty hidden syringe that poked you from inside the mattress as you lay down in a bed at a cheap hotel. Just threw a wrench in your life!
