Girls, Why random question from my ex during NC?

My wife divorced me 4 months ago, it was an easy breakup and during the divorce process I told her please do not contact me unless is for reconciliation, because I want to give us a chance, she was quite angry about it because she wanted stay friends but I told her once again please only talk to me if you want work things out. 2 months of NC has passed and yesterday she sent me a random message with a silly question about Gmail, and that she was at Disneyland with her daughter. I was quite nervous and confused, and I told her lets meet for a drinks she said no, I just answered "well you know where I stand for" and she didn't reply. It might be just a simple question but I wonder why she did that even I told her please contact me only to reconcile.
