Hey, so you said we'd deal with this "later" but I don't feel like it. Let's deal with it now.
Why do you think I am ISTp and how can you think I am the same type as my ISTp mom even though you know our relationship based on what I've described?
Our reactions to things are VERY different.
So, go ahead, explain.
(I really want an explanation -- I'm not really trying to challenge you, more trying to understand.)
