Daycare Mishaps

So while kids are in child watch I went to classroom for 1.5 hours, to give me sometime to run on treadmill.  When I went to pick them up teacher said Ang again got in a fight. She said after one reminder he did obey about not hitting.  Later on tonight during bedtime talk, he tells me the boy scratch his face and he hit him because of self defense.  There is always two side to every story.
