oops, posted too soon. I am way tired, and muh pinky....
Poke him every so often, and he'll reply 3 or 4 times to get your attention if you don't respond soon enough. It's almost cruel, but he IS totally aware you're doing it, because he'll accuse you of it while you ignore him.
I like to bombard him back n forth for a few then leave him hanging. Come back hours later to a crap ton of notifications from him. Poor guy needs a Teddy Bear and a pacifier.
