How this has effected everything!

This accident or act of violence on our dog/family member ahd just really effected all...I have screwed up where it cost me money...I had some sales and was giving a costumer her discount and them shipped the items later I noticed I refunded the full amount! That is was I get for being tired and over worked and doing business, well, I explained to the person and they said they understood with all I had going on and would pay and NOTHING...this is not a time for us to be able to soak this up. What have I done to get this karma. I have a husband working 60 out of 72 hours to get us out of dept and we are all effected...my kids are disappointed no holidays this summer or even a trip to the local movie theater but we are thankful to have Pepper. It would be nice if we could have the people who did this, I feel tired and bad about the whole situation but then I go off and do something that dumb and I am lucky enough to get a dishonest person. I am thankful for a the family and friends that have been here for support and a few kind words. When I have felt like giving up you guys have been here...Thank you.
