Big mistake

Today Kerry and me both made a stupid mistake, and that made all of what we'd done today should be re-done tomorrow. When I was serial-diluting honey and Kerry was preparing bacteria, she shouted suddenly. We BOTH forgot to dilute the honey previously, hence its concentration was too high and it's impossible to get any result the next day if we kept doing today. Strictly speaking this should be my fault as I'm serial-diluting the honey and should have noticed something wrong before this had happened...Sorry Kerry... T_T
