Truthful inner child

It is said we should nurture and cater to our Inner child and listen to our inner child,
Does that mean the Inner Child always tells the truth--
Does that mean we should do whatever the Inner Child feels like doing.

Sometimes, when I e-mail someone, (usually the same person)and I do not get a reply in a reasonable amount of time (which means IMMEDIATELY!!!) I get upset and hurt and I rail that the person does not like me.
A part of me — is it my Inner Child— wants to write a mean e-mail to the person railing at her for not liking me.
A couple of times I have written to her asking if she just doesn't want to talk to me, and she assured me again and again that she does, but she just gets busy.
Next time that happens, should I go ahead and do what my inner child wants and send the e-mail?
