['I was mad when I missed my credit card bill. I felt dumb', "Oh no! I've done that before.  Did you call them and ask for a grace period so you didn't build fines?  We all make mistakes like that so don't beat yourself up.", 'I did, I still felt bad though']
Those kinds of things are part of life and its better for our minds if we let them go and move on or see the humor in it.  I hope it didn't hurt your standing with the company.  You just reminded me to pay my internet bill! thanks!
