Tainted toothbrush

After repeatedly reminding Alex to go down stairs to brush his teeth this morning, he returned having forgotten what he was supposed to be doing down stairs and finally in frustration went into the upstairs bathroom and borrowed my toothbrush.  Kinda gross, but not a big deal as he is my son, but he has a cold and I wanted to avoid getting it and reminded him of this.  He then thoughtfully sanitized my toothbrush with liquid hand soap and replaced it.  I of course forgot about the incident until the taste of lavender and glycerin reminded me.  Yum, cough cough.
