I'm so annoyed with myself. Visited friend, and he talked about his ex girlfriend, if one can call her that. She has intimate contact to more people, including one of his friends, and had been telling him that she had given friend money. A fair amount. Ok, not optimal, because he doesn't really need it any more. Friend told me about the money he had received from her...
But then a bit later he started laughing at her and saying how she could never afford the things she intends to do (a legal necessity) and she isn't doing anything to earn money. I was horrified by his attitude and asked him how he could take money from  her when she can't afford it. He said he thought of it as a present.
Unfortunately I met her later. I told her she should be careful, that he doesn't need any more money, he has enough. She told me how badly he had treated her, and a lot more. She was drunk, as usual.
 I don't like this woman, but I think she is in some way handicapped and one shouldn't take advantage of her or laugh at her and make fun of her.
I shouldn't have stuck my nose in. It's not my business. The more I think about my behaviour, the more it annoys me. It was a chain of events, and I really have to find a way from stopping myself acting so impulsively. From being annoyed and thinking I have to save the world.
