Some people don't think saying these things mean anything...it's not that serious... They assume once you say it and say sorry bygones will be bygones....but no! Your partner will always remember your words. Don't let any amount of see-finish make you start saying these yamayama things and if you already do, please stop!
INSULTS
...Like "goat", "idiot"," mumu", "fool" ....mba nu. Don't do that. For some people calling someone "goat" is not a big deal....you might have done it growing up with your siblings or your close friends but please leave it there. That is abuse...e nor good.
