What I do in those circumstances is to point out the stuff I see that are "boring". 

Last time we had a get-together, the dude forgot to put some music on, so I pulled him to the side and said: 

> "Hey man, could we maybe get some music pumping ? Been wanting to show
> you X or Y artist".
>
> "Sorry bro my speaker is broken" (he never had a speaker) ",but nextime Ill >remember that"
>
> "So when's the next one gona be ? My place or your place ?"
>
> "Bla Bla Bla"
>
> "You bet, Ill be going then, Good Night Josh"

This is what I found that works the most while providing feedback, most extreme reaction I had was someone telling me that If I wanted to order pizza I would have to pay myself cuz they couldn't.

And you know what ? It was perfectly resonable.
