The boys finally got back on their bikes recently after being away from it for more than a year.  They both were nervous but became more comfortable the second time.  One Saturday night when the Kick the Can did not happen, I took the boys to ride the bikes to school.  They did well, but then Connor got too comfortable and went down the slope too fast.  He fell and scraped his knee.  The scrapes were just two quarter-sized circles, but unfortunately on day 3, some yellowish cloudy pus was oozing from them.  Now Connor is on cephalexin, an antibiotic, which tasted quite bad.  Fortunately Connor is good about taking medication; tomorrow will finally be the last day of it.
