Thanks Silence. I'm sorry for your loss too. My two blood related brothers got married and I was invited to the weddings and wasn't allowed to go to one of their receptions. Then my step sister was married and I wasn't invited at all. I could almost understand if I was really an immoral person or someone who caused a lot of disruption but as a mild mannered, kind person it basically just makes you angry and hurt.
At my younger brothers wedding my mom, step dad and I went together and we were only allowed at the wedding and then for a personal photo shoot while everyone else waited really far away from us. My mom had been disfellowshipped over twenty years ago and she never went back so she's still bad of course. But anyway, the elder who married my brother and his wife was her father. I don't really know him but you could tell that he's a very strict person. After we took the pictures I saw him standing far away but I made a split decision to go and introduce myself. As I cut across the grass to where he was I could see him tense up, lol, my mom followed right behind me too! He shook our hands and then nearly ran away as quick as he could, he was so rude, but I did like seeing him squirm a bit. If they want to make you feel like the lowest being on the planet then I say stick it in their faces rather than give them the satisfaction of being morally superior.
