People get fed up with boring messages and I Think you have no reason to worry as it was a positive and nice message. I am sure that she will respond once she is back online... please don't set yourself up for sad times waiting for a reply. Women love banter and fun so that's always a good way to start when chatting on dating web sites, once you get to know them a little, then is a good time to mention what attracted you to them.. Good luck and hope she replies x
