Nobody tells me what I’m going to do or where I will be going and when that happens
I am open to invitations or requests or suggestions where my involvement is desired or ostensibly necesary for somone else. But I will never respond to this as a statement of fact or in the form of a threat
My most enforced boundary is likely “if I clearly told you «no», do not insist”. Insisting further won’t just piss me off, but also decrease the likelihood that you’ll get what you’re asking for.
