It would make sense if it were upsetting, Etcetera1. Kinda like being 'triggered' when other people do it to you. You don't have to cut your best friend off - could you have a frank discussion with 'I feel upset when...' (putting it on you not on them, if that makes sense)

Re your question as to what if they ignore you... I don't know if I missed it but it is difficult without knowing (and I am not asking!) the people involved or context. It is different if it is your employer vs. your hairdresser, if that makes sense.

Sorry I missed it: 'unaware' - people are in their own world or self-involved and are not able to consider that their actions (or lack thereof) can have an impact on another. It's just not on their radar due to lack of empathy or consideration for another.
