The other person is busy all week .The other person does not like to apologize .None of the above choices .The other person has no way to contact them .
What may be the reason they are going to be waiting a long time for an apology ?
All i can do is call him that we are leaving for the sunday and last day of the convention and see what happens . Maybe he 'll realize what he says was wrong and apologies . It happened before . Once out of the other times .
