...quite often, I've found that listening to them works great.
I can sit down and listen to my NT friends when they are upset about something.
I try to see things from their view point, and offer logical advice or suggestions.
In doing this, I never tell them that they are wrong, and I keep everything calm and logical and constructive.
I try not to dwell on the thing that has upset them, but offer them a 'pathway' to more positive thinking.
(watch out for any desires they may have to upset/hurt someone else, to make themselves feel better)
Generally find myself saying stuff like.....
Ok, well, this thing has happened, and made you upset
the thing that upset you is done, it's happened, you can't change that
but you can decide how you move on from it
.....then if I can, I try to point out how he (or she, in your case) can move on in a positive way.
Also, if you keep in mind that you like the person, you can really help them with your views / suggestions.
