There are many, many ways to ‘point the finger’ at someone else.
Literally, of course.
But how about …
with a condescending tone;
with a more subtle tone of disappointment;
with judgmental body language;
with silence or even apathy;
with anger or frustration;
with resentment …
… the list goes on.
Just remember: every time you point the finger at someone else, you’re also, in some way, pointing it at yourself.
