Could you please help me to correct the following passage？ It depends. First, I will ask my manager if I can ask for a leave and attend the training in another day. If the manager tells me that it can be delayed, I will emailed the customer and tell he or she I'm available at 10 o'clock. And then I will attend the training in another day. If the training is too important to miss, I will email the customer sincerely telling him or her that I'm really sorry, but I have something really important at hand, I will definitely reply to you once I finished, and ask for forgiveness and understanding.and make an apology again.
