I make mistakes in attendance several times a month. Every time I go to the leader for signature, she doesn't say what I stand for.
I think you will make several mistakes every time you do attendance, although the leader doesn't explain every time he signs. He didn't mention you. I think maybe you have become a normal state. If nothing can represent this situation, you should reflect on yourself. If the leader doesn't say anything, you don't mean that he has no idea.
