Can the actions of others go in the R line?

Hi Brooke, I think I recall hearing you or one of your coaches say that we should not put someone else’s behavior in the R line…is that correct? I was recently coaching a client who wanted her R to be “sister acts more considerate towards me”. I tried to have her frame it in terms of something she could control. But it got me thinking about when an R is within our control or not – in my clients case there were likely many things she could do to have her sister be more considerate (make a request, set boundaries, be more honest etc) without being controlling. Was I wrong to push back on this R? Thank you!
