Hello @Prim&Proper . Thank you for reading my posts and for commenting. You are very welcome to post, Normally I get on well with SIL. I havent seen much of her this year, but she has been very ill and I have had problems of my own with OH Im pretty sure that my children are fully aware that I havent been invited. When they said they would come the weekend before Christmas they both knew that the other one was coming that weekend and I got the impression that they had purposely arranged it that way. Then it clicked that that was the weekend of SILs party. I know that they have both been invited (I overheard SIL inviting dau) and if they thought that I had been invited too then it would have been natural to mention it.
