What has he done wrong today?

Teacher told my mum that Shawn hit another kid. Another occasion of the day, a child placed his finger onto Shawn's mouth and Shawn took a bite. I am not too sure what had happened and whether it's the same child who got hit and bitten. When the teacher saw him taking the bite, the teacher exclaimed, "Shawn!" and he did his stance and roared like a lion. The teacher asked, "Who's naughty?". Shawn replied "Teacher!"

Something must have triggered him to react that way. I hope my mum would dig up more details. When he got back, mum and I kept reminding him it's wrong to bite and hit people. I did asked him who did he beat/hit and bite, his reply was "Zhi Yang" whenever I asked. O well.... whoever it is, I hope Shawn doesn't repeat this anymore!!!
