why... you should talk about it. communicate how you feel with words instead of attempting to communicate indirectly by acting out where the other person has to try and guess what they are supposed to have done wrong.

i understand the temptation to act out
to try and induce my feeling in another
by doing what i took them to have done to me

but the idea is to talk about it, yeah.

to say 'when you promised to call me back and you didn't i felt really hurt'
to say 'i felt like not coming in today so you would see how it feels to expect someone to be there for you and then find out that they are not'

it can be hard.
i find it easier to communicate by way of emails...
