i'm sorry

Don't all of us feel like that at one time or another? Perhaps we have non-trusting parents who jump to conclusions. They erroneously say something to or about us, then never try to take it back. Not that words can be taken back, but an apology, the acknowledgement would go along way.
Maybe our spouse says things that hurts your feelings.
Maybe your children forget your have feelings.
Maybe your friend gets snippy or uppity.
Maybe your co-worker was impatient.
Or maybe you were one or more of those.
It is nice to receive apologies, hugs and kinds words to make amends. But sometimes that doesn't happen. We don't always reach out when we're in the wrong, either.
If someone consistently walks on you, that is abuse. Don't wait for the apology, get out. But if someone hurts your feelings, address it. There is the very strong possibility that the other person doesn't know that your feelings were hurt. How can they say I'm sorry if they aren't aware?
