Tooth Fairy Failure

I would first like to brag about the fact that I am practically a professional tooth puller, and my daughter, Camryn, is a very brave little girl.  She has let me pull all 4 of the teeth that she has lost.  The tooth fairy did great for teeth 1 and 2, but failure set in on tooth 3.  The pulling of said tooth was very eventful.  We were in the office at the school and her top front tooth was hanging on by the front root and I could not get it out.  My crafty assistant director (who gets completely grossed out by the topic) suggested using dental floss to loop around it and then pull both ends close to the root to get it out.  It took two tries, mostly because I was a little nervous, but worked like a charm.  That night we put it under her pillow and I proceeded to totally forget about putting the dollar under her pillow.  She came up the next morning in tears.  She wondered what she had done wrong to be skipped by the tooth fairy.  I felt terrible, but with the idea from yet another great friend, we snuck a dollar under her pillow at bath time and suggested she check one last time before going to bed.  She was so confused and delighted when she found it.
Now fast forward to Tuesday night of this week.  She had been saying for a couple of days that one of her bottom teeth was very loose.  We were brushing teeth and I realized just how loose it was.  Again, the tooth was hanging on by a thread and I could not get it with my fingers so we used the dental floss trick again with perfect success.  It was actually pretty late for her bedtime so I was not far behind her going to bed thus totally forgetting my tooth fairy duties AGAIN!!
Her comment to me the next morning was priceless.  She waltzed into the bathroom where I was baggie holding tooth in one hand and the other hand providing complete inflection and said "Not a penny, not a nickel, not a dime, or a quarter, and certainly not a dollar.  I got NOTHING from the tooth fairy"  We could not attempt the same strategy as last time because she looked high and low this time, but I was saved by my wonderful husband this time.  He told her that she lost the tooth so late in the day that she must not have made it on the tooth fairies list for the night and we will just have to try again.  Fortunately, I remembered the next night, but I am feeling like the worlds worst mom.
My sweet daughter unknowingly made me feel even worse when she realized her brother was bummed about not getting a dollar and she gave her tooth fairy money to him.  I sure love that girl.
