My friend, after years and years of suffering, finally got his eternal peace today. His wife will be buried at the Central Cemetery after she passed away at 4:51am.
What are you intending to say with this? I am guessing you have a bad joke in here somewhere.
It means she was totally annoying and he is now better off with her being dead.
The opinion of yours stating that the deceased was annoying and the husband is now at peace is really not very nice. What if you were the husband, would you think it was okay to joke about his wife? He would feel very injured mentally by the remark.
