Because of your phrasing. You always come across as hostile and defensive, specially when somebody disagrees with you
Yes you can ask whatever you want but that does not mean I have to answer, or that your question isn't rude . Like I said before what you said is implying you wanted to work out why and tell me why you though she was hurt, if you had phrased it differently then it would have come across very differently. Not asking that question to help and instead to try and jump to your own conclusion about whats happened, does not come across better
I am not saying this to be nasty, I genuinely think you should have a hard look at how you talk to and treat other people
