With other Iranians, I have no problem reading and sending social cues; with non-Iranians taarof makes me come off as super nice and kind. But what happened, when people repeatedly took me on on my taarofs, I grew silently very spiteful and distanced myself from them. If a guest is staying late we never ask them to leave, we ask them to stay for dinner and that is a cue that I am about to inconvenience myself and you have to leave, but more often than not, in situations like this, I ended up having a guest over for hours and then overnight lol.

It took me a while to rewire my brain to set the boundaries explicitly, and I have to admit it is still excruciatingly painful for me to reject someone; makes me feel very rude. Nonetheless this approach works great, I dare say a more straightforward culture allows for a better mental state by allowing explicit and clear boundaries for oneself.
