2. I can't go to the training because I need to help my parents with something at home. When the leader arranges this training, he will basically ask your permission first and will communicate with you. You have to show your situation to the leader, and everyone will understand. For example, if you can't go to training in an emergency at home, you can explain the situation. Of course, if you just don't want to go, you should think of a good reason to ask for leave.
