My FIL and fiancés step mother irritate the shit out of me, we invited them over yesterday to spend time with us and our daughter because it's been a while since we've seen them and we hate going to their house because people smoke it it, it's freezing and we will just sit in silence the whole time. They declined the invite and said his dad was having kidney problems and we're going to stay home, they went over to his grandparents and drank instead. Yet they will post on fb bitching about how they miss us and never get to see us even if they saw us 3 days ago, it irritates the shit out of me.
Next time they post about missing you, comment and say "I know, maybe next time there won't be a drinking party to keep you from taking up our invitation to visit! :)" lol
