W has been a bit chatty yesterday and today via IM... struggle with not responding (feel like I'm being cold and standoffish if I don't) is this a bad thing?

I usually wait a bit but the impatience gets to me and usually cave within the hour. some of it has been regarding D, some of it is just casual chit-chat about work or news. She always initiates.
