He got hurt

My son got a small accident tonight. I was at school and when I got home I saw him putting warm towel on his lips. I asked him what had happened and he said that he hit his lips when he was trying to open the bottle of Gatorade drink. His lip was bleeding and has a big bump on it. I would like to get mad but I hugged him instead. He was bleeding and I knew it hurts. I told him to just be careful next time and I do not want him to get hurt. He went to bed without brushing his tooth he cannot do it. Poor son!
