I'm out to my family and nearly all my friends, and they've been supportive, or at least accepting. But I have two friends, good ones, to whom I haven't come out before now, because I see them mostly at group and family events where it would be too awkward; I've been trying to get together with them one-on-one for some months now, but their lives are, erm, complicated, and it hasn't happened.
So last night we had them over to dinner -- they finally had a break from all the (exhausting) "complications" in their lives, and they were really up for having some people feed them a very good dinner and generally fuss over them.
It was a great evening, and I did come out to them. They asked a lot of the usual questions (none of the tacky ones, bless their hearts), and the more taciturn one was pretty much "Oh, OK, that makes sense -- cool." But Mary, who's pretty effusive, said "This is fantastic -- now I know why you've been looking so GOOD lately!!"

She had quite a bit more to say, but she kept coming back to that: how much I've changed for the better, and how she couldn't figure out why before now.
I loved it.
