Of Things We Cannot Take back

Daddy going to work was never an issue with our 3 year old.  She's used to that. But today she said,  "Don't go to work Papa.  Don't leave me in the home.", and it's not even the work week/day yet. I think she understood what happened the other night.
Two nights ago, we turned off all the lights and relied on the moon beams to light our bedroom window like what we usually do. We stayed on bed and asked each other questions about how our day went. It was our nightly family time. Then we heard noises coming from the window,  about 2 feet where we were lying down.  A man was maybe halfway inside the window of our bedroom already.  My husband immediately got up and yelled to make the stranger leave. He left instantly. We don't know who he was as it was very dark that time nor any idea of his intentions trespassing in our private space.

The trespasser left with nothing but took away our sense of security, nights peaceful sleep, my sanity and our child's confidence that she's safe inside the house even if her Dad is not around -- things that we can never take back.
I wonder what is going through inside our child's head right now and how this incident will affect the days to come.  I hope she can express herself more so that we can better understand and properly process her (traumatic) experience. It's difficult for us adults to move forward after stressful events.  What more for the innocent child  who only knows honesty, peace and love!?
