Congrats on 108 days that is awesome!
Learning to detach from others behaviour comes in time. I know for me that the stuff that use to bother me doesn't affect me as much as it use to. I use to let things at my work place bother me all the time and not only that but I would let what happened to others bother me as well. I would stew about it all night while getting plastered!
However, I have come to realize that I did that so I would have another excuse to drink. For me, life is just too short to worry about this sort of crap. Because at the end that is what it is. Someone elses crap that I don't want to take on. Because people that dish out crap have their own crap they are hiding or worrying about. Boy, that is a lot of crap, see what I mean? Hope this makes sense!
