What did she say??

My oldest daughter started first grade a couple weeks ago. Unlike many other places the kindergarten here is still only half a day. So needless to say she was not used to the all day class schedule. Despite my best efforts the bed time I set for the first day of school was not enough sleep. She came home exhausted. She was nodding off on the couch, and as bad as I felt for keeping her awake, I didn't want her to sleep before dinner time. We were at her father's house and Maria told her to go out and play or something dinner would be done in a few minutes. So out to ride her bike it was. A few minutes later Maria stepped outside for a "breather" and Kynndra was parking her bike. Maria told her she didn't have to park her bike, dinner wasn't done just yet. Kynndra told Maria she couldn't ride anymore. Maria asked why. And what else would come out of my little angel's mouth but, "I can't because I'm just to F-ing tired" Now I must make it clear that she did not say the actual word!! She did infact say EFFING!! Holding back laughter she was told that even though that was not a bad word, that adults use it to replace a bad word and she probably shouldn't say it. She was okay with that and went on into the house.
