Meh, don't sweat it. I suspected as much anyway. steve asked me to tell that he loves you and is sorry that he missed you before (presumably) going to sleep a few minutes later.
Although if I was a dick about it, I would make an observation that surprisingly many people go away from IRC soon after I'll say so much as 'hello', even when it's one of those "Who's gonna be on IRC tonight" deals. It's cool of you guys to actually give a reason.
