This: MIL said she was going to SIL’s house to baby sit. Later, hubby brought it up at dinner how MIL had enjoyed at the mall. She was like, if I had known we were going to the mall, I would have asked you guys to come also." Hubby said, “But ammi you told me two weeks ago that you were going to the mall.”
She lied. Twice.
I wasn’t expecting to be invited but why lie about it… Its offensive when people lie several times just to avoid inviting you.
