Being late to class is acceptable. It's something that happens to everyone every once in a while.
But being really really late to class is less acceptable.
I have a Monday and Wednesday class that meets from 10:20-11:40 AM.
Tell me why this girl showed up at 11:25 on Monday. We didn't have anything to turn in. There was no reason for her to arrive that late. I legitimately don't understand this.
You were there for fifteen minutes of an hour and twenty minute class. You should have just stayed at home.
