My A in others’ C

So let me get this straight: when I give someone else words, money, support, etc. that comes from my A-line and goes in their C-line. This means the only “effect” I’m ever having on someone else is as a C. The rest of theirs and my model is something we fill in for ourselves respectively, conscious or not, right? Sometimes my brain still tells me I can predict/anticipate someone else’s Ts and Fs based on my As/their Cs and then I confuse myself into believing I can influence/control their whole model, when actually the only place I ever show up in someone else’s model is through the C line. Can you check my math on this? Thanks!
